COLORED RESIN MICROPARTICLE AND METHOD FOR PRODUCING AQUEOUS COLORED RESIN DISPERSION

摘要

PROBLEM TO BE SOLVED: To prepare an aqueous colored resin dispersion which enables the preparation of an ink capable of giving high-density recording being free from bleeding, excellent in fastnesses such as water resistance and light resistance, and good in long-term storage stability.

SOLUTION: The method for obtaining the aqueous colored resin dispersion comprises dissolving or dispersing in a polymerizable unsaturated monomer a colorant having an affinity for the polymerizable unsaturated monomer and emulsion-polymerizing the solution or the dispersion in the presence of anionic and/or nonionic reactive emulsifiers to obtain colored resin microparticles, and dispersing the colored resin microparticles in an aqueous medium.
