WATER-CASED PRINTING DYE, SET OF REACTION LIQUID AND WATER-BASED PRINTING DYE AND IMAGE FORMATION METHOD

摘要

FIELD: polygraphy.;SUBSTANCE: invention relates to water-based printing dye used in the set of reaction liquid with water-based printing dye for image formation. The water-based printing dye is proposed making a part of the system using a reaction liquid including, at least, a polyvalent metal and water-based printing dye comprising, at least a pigment dispersion wherein the pigment is dispersed in anionic polymer disperser. Here note that the water-based printing dye meets the specified requirements.;EFFECT: production of a stable jet printing irrespective of the printing conditions, formation of uniform image with a high resistance to deterioration, clear image even in two-side printing, high-quality image sharpness.;18 cl, 1 tbl, 10 ex
