Abstract
The invention relates to a jet ink composition containing a leveling agent. The composition comprises a coloring agent, a water-soluble organic solvent, deionized water and a leveling agent. The coloring agent is a pigment or a dye, the leveling agent is selected from fluorine-containing surfactant polymer BYK340, acrylic modified fluorocarbon polymer compound EFKA3500 and/or fluorocarbon modified organosiloxane EFKA3034. The image printed by use of the inventive jet ink composition containing a leveling agent has a greatly improved color density, no color bleeding, high glossiness, and no burr at character edges.
Description
Technical field
The present invention relates to the ink that ink-jet printer is used, more particularly, relate to water-based jet ink composition, relate in particular to the water-based jet ink composition that contains flow agent.
Background technology
Along with the development of electronics technology, ink-jet printer uses more and more general in family and office work in recent years.Spray ink Printing is a kind of non-back-strike print method, and it is according to the electrical signal that microcomputer produces fine ink droplet to be ejected on the print media.
Generally speaking, ink-jet printing ink contains tinting material, water-miscible organic solvent and/or solvent borne organic solvent, tensio-active agent etc., and tinting material can be pigment or dyestuff.
In ink jet printing process, improve OD (colour density) value of print image, normally adopt the method that increases dispersible pigment color paste or dye paste consumption.But when the consumption of dispersible pigment color paste or dye paste was increased to certain value, even continue to increase color paste consumption, the OD value also no longer improved again.And the solvability of mill base is limited, and when being increased to when a certain amount of, mill base can be separated out from ink.Method shown in the Japanese kokai publication hei 8-337748 communique produces effect although the dye paste that suppresses dye ink separated out, and is undesirable to paint ink.And there is the not good enough defective of smoothness, reflecting feel and erasibility usually in the image that paint ink is printed, and there is the shortcoming of weathering resistance, poor water resistance in the image that dye ink is printed.In addition, when colour print, also there is the bleeding phenomenon between the different colours, the jagged phenomenon in printing character edge.
Summary of the invention
Problem in view of above-mentioned prior art, the method of a kind of new raising colour density of demand and water-based jet ink composition that can print high quality images, described high quality graphic refers to: the colour density of image is high, without bleeding, glossiness is high and the literal edge without burr.
The object of the present invention is to provide a kind of method of new raising colour density, and a kind of new water-based jet ink composition.The method and composition can print the high quality graphic that meets above-mentioned requirements.
Specifically, the present invention in water-based jet ink composition, add be generally used for plaing in coating, the paint etc. the tiling and sprawl the flow agent of effect, but produced unexpected effect.The image that the composition for ink that obtains like this prints has unexpected good colour density and, literal edge high without bleeding, glossiness without burr.
A first aspect of the present invention provides a kind of water-based jet ink composition, it comprises following composition: tinting material, water-miscible organic solvent, deionized water and flow agent, it is characterized in that, described tinting material is pigment or dyestuff, and described flow agent is selected from lower at least a: fluorochemical surfactant polymer B YK340, acrylic acid modified fluorine-carbon macromolecule compd E FKA3500 and fluorine-carbon modified organo-siloxane EFKA3034.
