COLORING MATERIAL DISPERSED LIQUID AND PHOTOSENSITIVE COLORING RESIN COMPOSITION

摘要

Provided are: a coloring material dispersed liquid which has excellent storage stability; and a photosensitive coloring resin composition. This coloring material dispersed liquid exhibits excellent plate-making characteristics when a color film is formed using the photosensitive coloring resin composition. This coloring material dispersed liquid is characterized by containing at least a coloring material, an acrylic copolymer and an organic solvent, and is also characterized in that: the acrylic copolymer comprises at least a structure having an ethylenically unsaturated group in a side chain and represented by formula (A) and a structure having a tertiary amino group in a side chain and represented by formula (B) and/or a structure having a quaternary ammonium salt in a side chain and represented by formula (C), a structure (D) having a carboxyl group in a side chain and a structure (E) having an aromatic ring; and the acrylic copolymer has a base number of 5-70 mmol/100 g, an acid value of 50-120 mgKOH/g and a weight average molecular weight of 5,000-30,000 in terms of polystyrene as determined by gel permeation chromatography.
