Description
GF/KH
209~1~2 PRINTED SHAPED BODIES AND SHEETS CONTAINING GELATIN
AS WELL AS PROCESS AND MEANS FOR PRINTING
The present invention relates to shaped bodies and sheets which altogether consist of gelatin or at least the outer layer of which consists of at least 5% of gelatin or chemically modified gelatin, and especially to hard and soft gelatin capsules and sheet gelatin, which have been printed by using the ink jet process, and to processes for printing these shaped bodies and sheets and to inks for conducting the process.
Shaped articles which altogether consist of gelatin or at least the outer layer of which completely or in part consists of gelatin, and especially hard and soft gelatin capsules, once manufactured, are printed to an increasing degree. This, above all, is done for labelling, identifica-tion and codiny purposes and for providing evidence of the origin. The usable print methods basically include embossed printing, gravure printing, screen printing, laser printing and, more particularly, in the case of gelatin capsules to an increasing degree, ink jet printing. This is due to the fact that the printing techniques other than ink jet printing require application of mechanical and thermal load which may damage the final capsules. Another drawback is the occurrence of staining spots and streaks that may be caused upon contact of the freshly printed capsules after the printing station~
The ink jet process is especially preferred for gelatin cap-sules because it enables contactless printing and thus, goes easy on the product. Printing rollers and rubber rolls are no longer required. The ink jet process also allows round shaped articles such as, for example, gelatin capsules filled 2~981~2 with bathing oils to be provided with larger prints, although the surfaces thereof are much curved.
The inks hitherto used for ink jet printing of hard and soft gelatin capsules consist predominantly of water. In addition, they contain further solvents such as, for example, ethanol, isopropanol and propylene glycol and viscosity-in-creasing polymers such as, for example, cellulose deriva-tives. As the colorants there are mostly used readily water-soluble organic dyes.
From Derwent's abridged edition 86-090677/14 of JP 61-035-989-A, there is known an ink jet process, wherein the ink-bearing material such as gelatin, casein, starch, gum arabic, sodium alginate, poly(acrylic amide), PVP, poylur-ethane, CMC, or polyester is coated with an ink-permeable layer of a somewhat less hydrophilic material such as poly(vinyl acetate), polyethylene or PVC. However, this pro-cess is completely unsuitable for printing gelatin capsules.
From DE-A-34 11 136, there are known thixotropic gravure printing inks having a resinous binder, pigment and a solvent system, wherein flowability is modified, for exam-ple, by aluminum salts of alkane carboxylic acids, most fre-quently in admixture with fatty acids and other ingredients.
Such inks are completely unsuitable for the ink jet process.
One drawback inherent to the ink jet process resides in the fact that gelatin capsules, especially those having a capsule filling containing liquid hydrophilic components such as water, ethanol, propylen eglycol or poly(ethylene gly-cols), when stored tend to give off some ink jet ink to adja-cent other capsules so that so-called "ghost images" or staining spots and parts of the typeface will appear thereon mirror-inverted. Similar phenomena are also observed with gelatin sheets. Here, gelatin sheets, more specifically, are understood to mean "sheet gelatin" which is used as food ` :`

Such inks are completely unsuitable for the ink jet process.
One drawback inherent to the ink jet process resides in the fact that gelatin capsules, especially those having a capsule filling containing liquid hydrophilic components such as water, ethanol, propylen eglycol or poly(ethylene gly-cols), when stored tend to give off some ink jet ink to adja-cent other capsules so that so-called "ghost images" or staining spots and parts of the typeface will appear thereon mirror-inverted. Similar phenomena are also observed with gelatin sheets. Here, gelatin sheets, more specifically, are understood to mean "sheet gelatin" which is used as food ` :`
- 3 ~ 209~1~2 product. Since printed sheets thereof are closely stacked in the package, the occurrence of the so-called "ghost images"
is favored.
Therefore, it is the object of the invention, to improve ink jet printing to the effect that such drawbacks are eliminated and the ink deposited by the ink jet process remains durably and firmly adhered to those locations where it has been deposited, so that it cannot be inadvertently transferred to other capsules or sheets being in contact therewith.
It was now found that this object may be well and easily attained by that the inks contain an aluminum com-pound and/or a calcium compound. Preferably, the inks con-tain an aluminum compound. Preferably, in particular, the inks contain an alkali metal aluminate as the aluminum com-pound. Particularly good results are achieved with the dyes Carminic Acid (E 120), srilliant Blue (E 133), Allura Red (E 129) and mixtures thereof. However, in principle any other dye allowed under the pure food law regulations is usable if it is capable of reacting with aluminum ions and calcium ions to form aluminum salts and calcium salts or the so-called aluminum lakes and calcium lakes which to an optically sufficient degree stand out against the printed shaped articles, and especially the capsules. Thus, there may also be used Tartrazine (E 102), Quinoline Yellow (E 104), Sunset Yellow S (E 110), Fast Red C (E 122), Amaranth (E 123), Cochineal Red (E 124~, Erythrosine (E 127) and Indigotin (E 132). Further dyes may be taken into consideration, because of different legal provisions, for printing shaped articles to be used for cosmetic pur-poses. Some of these dyes are especially suitable for shaped articles and gelatin capsules dyed with the con-trasting color of said dyes. The ink jet ink may addition-ally contain colorant pigments such as titanium dioxide, by means of which bright characters or marks may be printed on ~ 4 ~ 20981-~2 dark-colored capsules. It has been shown that especially soft gelatin capsules which contain solvents such as water, ethanol, propylene glycol, glycerol, and poly(ethylene gly-cols) tend to subsequently give off part of the ink printed thereon to other capsules. This trouble is no longer or very much less observed with the inks according to the in-vention containing an aluminum compound and/or a calcium compound. The aluminum compound preferably is an alkali metal aluminate, among which sodium aluminate and potassium aluminate are considered in principle.
The above-mentioned dyes Carminic Acid (E 120), Brilliant Blue (E 133) etc. are also commercially available as aluminum lakes. Within the scope of the invention it is basically possible to dissolve these colored lakes in lyes, e.g. in caustic soda solution and caustic potash solution or ammonia, and then to admix the resulting solution with further solvents and/or dispersants. The ink jet inks thus prepared, when printed on hard or soft gelatin capsules or sheet gelatin, do not produce any ghost images. Since the dye contents of the commercially available aluminum lakes generally are not very high, the pure dye is preferred as a starting material for the preparation of the ink jet ink.
The hard and soft gelatin capsules preferably printed according to the ink jet method contain from 5 to 100% of gelatin, and preferably from 20 to 100% of gelatin.
In addition to the naturally occurring gelatin, a chemical-ly modified gelatin, for example succinylated gelatin, is often used in order to attain certain properties. Accord-ing to the invention, by using the ink jet method, not only type characters such as letters and numbers, but also com-panies' emblems or decorations may be printed.
Preferred shaped articles according to the inven-tion and especially soft gelatin capsules printed by the ~ 5 -2 09 81 ~2 ink jet process are illustrated in greater detail in the examples as set forth hereinbelow.
Example 1 14.5 g of aluminum chloride hexahydrate is dis-solved in 250 g of water, and 29 g of a 25% aqueous sodium hydroxide solution is added thereto. The pH value of the solution is about 8. The precipitate of aluminum hydroxide is centrifuged off, washed with water and then re-dissolved with 2% aqueous sodium hydroxide solution. 25 g of Carmin-ic Acid (E 120) is added to the freshly prepared stirred sodium aluminate solution and dissolved therein. After filtration, the pH value is adjusted to about 10.5 using 25% aqueous sodium hydroxide solution. 11.0 g of hydroxy-propylmethylcellulose dissolved in 245 g of water is added to the resulting solution. There is further dropwise added and admixed with stirring 67 g of propylene glycol and 150 g of isopropyl alcohol. Thereby, 1 kg of an ink jet ink is formed which is excellently processable and no long-er produces any "ghost images".
Example 2 In the same manner as described in Example 1, an ink is prepared using Brilliant Blue (E 133). The gelatin capsules and gelatin sheets printed with this ink likewise do not show any disturbing "ghost images".
Exam~le 3 33.3 g of Brilliant Blue (E 133) is dissolved in 200 g of water, and the solution is passed through a cation exchanger to prepare the dye acid from the dye disodium salt. Subsequently, the ion exchanger is washed with 340.7 g of water. The pH value of the thus obtained dye solution is about 1.2. 14.0 g of calcium chloride and - 6 - 209gl~
is favored.
Therefore, it is the object of the invention, to improve ink jet printing to the effect that such drawbacks are eliminated and the ink deposited by the ink jet process remains durably and firmly adhered to those locations where it has been deposited, so that it cannot be inadvertently transferred to other capsules or sheets being in contact therewith.

4.0 g of calcium carbonate are dissolved therein, and the pH value i5 rising to about 6Ø To this solution is added 11.0 g of hydroxypropylmethylcellulose dissolved in 150 g of water. In addition, 67 g of propylene glycol and 180 g of isopropanol are added dropwise and stirred in. In this fashion, 1 kg of ink jet ink is formed which can be pro-cessed excellently and which only very occasionally prod-uces faint "ghost images".
Comparative Example An ink having the same composition and containing Brilliant Blue (E 133) as the dye, but without addition of alkali metal aluminate, likewise provides good printing results; however, "ghost images" are observed to a consid-erable extent. The same is true for an ink according to example 3 which, however, contains the disodium salt of the dye acid.
