Abstract
The present invention relates to a water-soluble black ink for ink jet printers, which is prepared from 1 to 10% of water-soluble pigment, 0.01 to 5% of interfacial active agent, 0.1 to 1% of preservative, 10 to 40% of organic solvent and balance of deionized water, wherein the organic solvent is formed by compounding a ketone and an alcohol according to a specific proportion and used for enhancing the stability of the water-soluble black ink.
Description
(1) technical field
The present invention is a kind of black pigment ink, refers to a kind of water-soluble black ink that is applicable to the high-order ink-jet printer especially.
(2) background technology
Grow up fast with the internet along with PC is universal in recent years, ink-jet printer also almost has been product indispensable in the present personal computer equipment.Concerning general user, the ink-jet printer of a basic model just is enough to deal with the demand of its general file.Yet except the function of printer itself, the selection of ink, consumptive material, print paper, and use-pattern will determine whether quality and the printer printed can life-time service.
The black pigment that the conventional ink jet printers ink is selected for use mostly is water-soluble dye, and the water-soluble dye advantage is to be easy to disperse in the water, on the production processing also than being easier to.Dissolubility is splendid again because of water-soluble dye, does not cause spray orifice to block and the problem that can't print takes place so do not have the dry skinning of shower nozzle; But also because the dissolubility again of its water-soluble dye is splendid, so when the ink spray printing runs into water easily and makes font fuzzy after paper, though this can improve its water fastness on paper by the structure that changes dyestuff, but still can't reach hundred-percent effect.
When black pigment was selected water-soluble pigment for use, this ink just had splendid water tolerance, and very ripe with the dispersion technology of black pigment now, so the water-soluble pigment in this ink also has suitable stability.But for dispersive pigment in the water, it has a characteristic, no matter promptly the stability of pigment in water why, the phenomenon of all can flocculating along with the growth of storage period of the pigment in the water will be if the agglutinating matter increase then will make pigment particle size become big gradually and precipitate.Again when the ink that contains this water-soluble pigment be applied to runner and spray orifice aperture all less than the ink gun of 30 microns (30 μ m) on the time, in case block then can cause whole shower nozzle to block or damage and influence printing quality, so the stability when selecting for use suitable ink composition to improve to store and using is essential.
Therefore, how to develop a kind of above-mentioned shortcoming of avoiding, and improve the water-soluble black ink of stay in grade degree, real in pressing for the problem of solution at present.
(3) summary of the invention
Main purpose of the present invention provides a kind of water-soluble black ink that is applied to ink-jet printer, and it is by the adding of organic mixed solvent of a specified proportion, in order to improving this black ink stability, and prevents the shower nozzle skinning and increases printing quality.
For reaching above-mentioned purpose, the invention provides a kind of composition of water-soluble black ink, it comprises: one is 1～10% water-soluble pigment by weight; One is 0.01～5% interfacial agent by weight; One is 0.1～1% sanitas by weight; One is 10～40% organic solvent by weight; And one be 44～88.89% deionized water by weight, and wherein, this organic solvent is made up of a ketone and an alcohols.
The present invention also provides a kind of water-soluble black ink, and it is by (1) water-soluble pigment, 1～10%; (2) interfacial agent, 0.01～5%; (3) sanitas, 0.1～1%; (4) organic solvent, 10～40%; And (5) deionized water is formed.Wherein this organic solvent also comprises the ketone with heterocyclic and has the alcohols of the straight chain list alkylol cpd of 1～5 carbon, forms according to the specified proportion allotment, is allocated as best effect with 1: 2 specified proportion in the present embodiment.In practical application, this ketone with heterocyclic can be selected from a pyrrolidone, monomethyl pyrrolidone, a pyrrolidone compound or its mixture; This alcohols then can be selected from straight chain list alkylol cpd, the two alkylol cpds of straight chain or its mixture with 1～5 carbon.Certainly this interfacial agent is to be a non-ionic type or a both sexes ionic interfacial agent.
The present invention also provides a kind of black ink composition that is applied to ink-jet printer, it is made of by organic mixed solvent of 10～40% by weight a water-soluble colorant solution and one, this organic mixed solvent is formed in 1: 2 ratio with the alcohols with 1～5 carbon straight chain by having heterocyclic one ketone, in order to improve the stability of this black ink composition, wherein, this water-soluble colorant solution comprises: one counts 1～10% water-soluble pigment with this black ink composition weight; One counts 0.01～5% interfacial agent with this black ink composition weight; One counts 0.1～1% sanitas with this black ink composition weight; And one count 44～88.89% deionized water with this black ink composition weight.
Be clearer understanding purpose of the present invention, characteristics and advantage, the present invention is described in detail below in conjunction with accompanying drawing.
(4) description of drawings
Fig. 1 is the basic comprising composition weight fraction figure that discloses water-soluble black ink of the present invention.
(5) embodiment
The present invention is the organic mixed solvent that is applied to the water-soluble black ink for a kind of, though following examples illustrate the utilisation technology of the organic mixed solvent of the present invention with the black ink of ink-jet printer, yet the black ink that can use the technology of the present invention is not limited to the water-soluble black ink of ink-jet printer, any black ink that is suitable for following technical characterictic all can be incorporated reference at this.
See also Fig. 1, it is the basic comprising composition weight fraction figure that discloses water-soluble black ink of the present invention.As shown in Figure 1, this water-soluble black ink is by (1) water-soluble pigment, 1 ~ 10%; (2) interfacial agent, 0.01 ~ 5%; (3) sanitas, 0.1 ~ 1%; (4) organic solvent, 10 ~ 40%; And (5) deionized water is formed.Wherein this organic solvent then is the alcohols that is had the straight chain list alkylol cpd of 1 ~ 5 carbon by a ketone and with heterocyclic, forming according to specified proportion allotment, is allocated as best effect with 1: 2 specified proportion in the present embodiment.In practical application, this ketone with heterocyclic can be and is selected from a pyrrolidone, monomethyl pyrrolidone, a pyrrolidone compound or its mixture; This alcohols then can be selected from straight chain list alkylol cpd, the two alkylol cpds of straight chain or its mixture with 1 ~ 5 carbon.Certainly this interfacial agent is to be a non-ionic type or a both sexes ionic interfacial agent.
Yet in aforesaid constituent, this water-soluble pigment is to have disperseed the high density black pigment finished for one, as TMB-300, TMB-800, CAB-O-JET 200, CAB-O-JET 300, Hostafine BlackO-PT and Acryjet Black-357 etc., be a commercialization material, can in market, buy easily.And a small amount of interfacial agent that is added can allow the sticking power between pigment and paper improve when its function then is to make ink printed to paper, increases water tolerance.As previously mentioned, its source can be selected non-ionic type or amphoteric ion type interfacial agent for use, for example Surfonyl 440, Surfonyl 465, Pannox 19, Pannox 122A, ABLUTER CPS ... Deng.Because this interfacial agent is all a commercial material, so no longer describe in detail in this.
The present invention mainly has the alcohols that heterocyclic ketone and has the straight chain list alkylol cpd of 1 ~ 5 carbon by one, specified proportion allotment according to 1: 2 forms, and with in 10% ~ 40% the weight ratio adding water-soluble black ink, in order to the stability of raising water-soluble black ink, and prevent the shower nozzle skinning and increase printing quality.For further specifying technology contents of the present invention, please refer to the following example explanation.
