[0109] [Preparation method of dispersion liquid composition for ink]

[0110] The ink dispersion composition according to the present embodiment can be prepared, for example, by the following two methods.

[0111] (1st production method)

[0112] In the first preparation method, after mixing and dispersing a dispersion liquid containing a water-insoluble colorant, a water-soluble polysaccharide compound, and water, and a dispersion liquid containing a dispersing agent, an antifoaming agent, a preservative, and water, the dispersion liquid is dispersed. The liquid is mixed with an aqueous solution containing a polyvalent metal salt and dispersed, whereby a dispersion liquid composition for ink is obtained.

[0113] More specifically, a dispersion liquid containing a water-insoluble colorant, a water-soluble polysaccharide compound, and water is mixed with a dispersion liquid containing a dispersing agent, an antifoaming agent, a preservative, and water, and glass is added to t...

Abstract

Provided are: a dispersion liquid composition for ink containing a non-water-soluble coloring agent, a water-soluble polysaccharide compound, a multivalent metal salt, a dispersant, and water; and an ink composition containing the dispersion liquid composition for ink. Also provided are an inkjet printing method using the ink composition, an inkjet printed article printed by the inkjet printing method, a sublimation transfer dyeing method using the inkjet printed article, and a sublimation transfer dyed article dyed by the sublimation transfer dyeing method.

Description

technical field [0001] The present invention relates to a dispersion liquid composition for ink and an ink composition. Background technique [0002] With the development of digitization of information, ink jet printers have been widely used as printing presses for offices and homes. In addition, a large number of applications in commercial printing or textile printing have been advanced in recent years. In addition, with the widening of applications of inkjet printers, various colorants such as water-soluble colorants such as acid dyes and direct dyes, and water-insoluble colorants such as disperse dyes and pigments have also been used as colorants for inks depending on the application. agent. [0003] Disperse dyes are widely used in industrial dyeing of hydrophobic fibers such as polyester, which are dispersed in dye baths or color pastes for dyeing. The dye penetrates and diffuses into the fiber in a dispersed state under high temperature conditions, and is colored by...
