Abstract

The invention concerns inks for letterpress or offset printing which contain microcapsules containing the colour formers, alkali-metal salts of colophonium as binders and glycols or glycol ethers as solvents.

Description

Die Erfindung betrifft Mikrokapseln enthaltende Druckfarben für den Buch- oder Offsetdruck, die Mikrokapseln, Alkalisalze von Ko­ lophonium als Bindemittel und Glykole oder Glykolether als Lö­ sungsmittel enthalten.The invention relates to printing inks containing microcapsules for Book or offset printing, microcapsules, alkali salts from Ko Iophonium as binder and glycols or glycol ether as Lö contain agents.

Als Mikrokapseln kommen alle gebräuchlichen Produkte in Betracht, bevorzugt werden Kunststoffkapseln in trockener Form verwendet. Im einzelnen seien beispielsweise Kapseln aus Polyamiden oder Polyurethanen und insbesondere solche aus Melamin-Formaldehyd- Harzen oder Acrylsäurederivaten genannt. Die Herstellung dieser Kapseltypen ist insbesondere aus der Patentliteratur bekannt. In der Regel enthalten die Kapseln Farbbildnerlösungen, die beim Zerstören der Kapseln mit den Nehmerseiten des Durchschreibesat­ zes Farbstoffe bilden. Nehmer und Durchschreibesätze sowie die Mikrokapseln sind Stand der Technik.All common products can be considered as microcapsules, plastic capsules in dry form are preferably used. In particular, capsules made of polyamides or Polyurethanes and especially those made from melamine-formaldehyde Resins or acrylic acid derivatives called. The making of this Capsule types are known in particular from the patent literature. In As a rule, the capsules contain color former solutions Destroy the capsules with the copy side of the carbonate satin zes form dyes. Takers and carbonless rates as well as the Microcapsules are state of the art.

Erfindungsgemäß enthaltene Bindemittel sind Kolophoniumderivate, im wesentlichen Alkalisalze der Abietinsäure, wobei als Alkali Kalium, Lithium und insbesondere Natrium zu nennen sind. Diese Bindemittel sind in den als Lösungsmittel verwendeten Glykolen und Glykolethern löslich. Einzelne Lösungsmittel sind beispiels­ weise Ethylenglykol, 1,2-Propylenglykol, Glycerin, Diethylengly­ kol, Dipropylenglykol, Polyglykole vom Molgewicht 200 bis 600, Ethylenglykolmono-methyl-, -ethyl- oder -butylether oder Mono­ ether von Polyglykolen. Gemische dieser Lösungsmittel sind eben­ falls geeignet. Bevorzugt sind niedrigviskose Lösungsmittel, wie z. B. Glycerin oder Propylenglykol.Binders contained according to the invention are rosin derivatives, essentially alkali salts of abietic acid, being the alkali Potassium, lithium and especially sodium are mentioned. This Binders are in the glycols used as solvents and glycol ethers soluble. Individual solvents are exemplary as ethylene glycol, 1,2-propylene glycol, glycerin, diethylene glycol kol, dipropylene glycol, polyglycols with a molecular weight of 200 to 600, Ethylene glycol monomethyl, ethyl or butyl ether or mono ether of polyglycols. Mixtures of these solvents are flat if appropriate. Low-viscosity solvents such as e.g. B. glycerol or propylene glycol.

Quantitativ sind die erfindungsgemäßen Druckfarben z. B. wie folgt zusammengesetzt:
10 bis 40 Gew.-% (vorzugsweise 15-30%) Bindemittel
20 bis 60 Gew.-% (vorzugsweise 25-50%) Lösungsmittel und
20 bis 50 Gew.-% (vorzugsweise 25-40%) Mikrokapseln.Quantitatively, the printing inks according to the invention are e.g. B. composed as follows:
10 to 40% by weight (preferably 15-30%) of binder
20 to 60 wt .-% (preferably 25-50%) solvent and
20 to 50% by weight (preferably 25-40%) microcapsules.

Die Mikrokapseln werden, wie bereits angegeben, vor zugsweise in trockener Form verwendet, da man so leichter die zur späteren Er­ zeugung des Schriftbildes nötige Konzentration erreicht. Die er­ findungsgemäßen Druckfarben erhält man durch Mischen der Kompo­ nenten, zweckmäßigerweise löst man zunächst das Bindemittel im Lösungsmittel und verrührt dann die Mikrokapseln in der Lösung.As already stated, the microcapsules are preferably in dry form because it is easier to use for later er generation of the typeface necessary concentration reached. Which he Inks according to the invention are obtained by mixing the compo  nenten, expediently first dissolve the binder in Solvent and then stir the microcapsules in the solution.

Zur Erzielung einer hohen Reibechtheit der Drucke ist es in der Regel zweckmäßig, der Druckfarbe noch einen Abstandshalter in Mengen bis zu 15 Gew.-%, vorzugsweise 5-10%, bezogen auf die Druckfarbe, zuzusetzen.It is in the to achieve a high rub fastness of the prints As a rule, the printing ink has a spacer Amounts up to 15 wt .-%, preferably 5-10%, based on the Printing ink to add.

Solche Abstandshalter sind ebenfalls aus der Patentliteratur be­ kannt, im einzelnen seien beispielsweise Titandioxid, Kunststoff­ kügelchen mit Durchmessern von 20-30 µ, Cellulosefasern oder kali­ brierte Stärke genannt.Such spacers are also from the patent literature knows, in particular, for example, titanium dioxide, plastic beads with diameters of 20-30 µ, cellulose fibers or kali called strength.

Überraschenderweise gelingt es, mit den erfindungsgemäßen Druck­ farben Papiere zu beschichten, mit denen man einwandfreie Durch­ schriften erhält. Insbesondere eignen sich die Druckfarben für den Spotdruck.Surprisingly, it succeeds with the pressure according to the invention to coat colored papers with which one can get through perfectly writings received. The printing inks are particularly suitable for the spot printing.

In den folgenden Beispielen beziehen sich Angaben über Teile und Prozente, sofern nicht anders vermerkt, auf das Gewicht.In the following examples, information about parts and Unless otherwise noted, percentages are by weight.

Beispiel 1example 1

35 Gew.-Teile Mikrokapselpulver (Mikrokapseln hergestellt gemäß den Angaben der EP-B-26 914, enthaltend eine Farbbilder-Schwarzmischung)
5 Gew.-Teile kalibrierte Stärke (z. B. Amyzet® KT, Firma Amylum, Belgien) als Abstandshalter
30 Gew.-Teile Natriumresinat (Kolophoniumsalz) und
30 Gew.-Teile Glycerin
werden in der Art vermischt, daß zunächst das Resinat im Glycerin gelöst wird und dann die Kapseln und der Abstandshalter ein­ gerührt werden. Man erhält eine farblose Druckfarbe, die im indi­ rekten Buchdruck auf die Geberseite eines Formularsatzes in einer Menge von ungefähr 6 g/m2 gedruckt wird. Beim Beschreiben des For­ mularsatzes, der als Nehmer eine Clay-Schicht aufweist, erhält man eine schwarze Durchschrift mit ausreichender Intensität. 35 parts by weight of microcapsule powder (microcapsules produced in accordance with the specifications of EP-B-26 914, containing a color image / black mixture)
5 parts by weight of calibrated starch (e.g. Amyzet® KT, Amylum, Belgium) as a spacer
30 parts by weight of sodium resinate (rosin salt) and
30 parts by weight of glycerin
are mixed in such a way that the resinate is first dissolved in the glycerol and then the capsules and the spacers are stirred in. A colorless printing ink is obtained which is printed in an indirect letterpress on the donor side of a set of forms in an amount of approximately 6 g / m 2 . When describing the form set, which has a clay layer as the receiver, a black copy with sufficient intensity is obtained.
