Title:
カラーフィルター用顔料分散組成物及びカラーフィルター用顔料分散レジスト組成物
Document Type and Number:
Japanese Patent JP7299069
Kind Code:
B2
Abstract:
In the present invention, when producing a pigment dispersion resist composition for a color filter based on a pigment dispersion composition for a color filter, the reduction in viscosity, viscosity stability, PGMEA resolubility, alkali developer solubility (potassium hydroxide aqueous solution solubility, and TMAH aqueous solution solubility) and heat resistance are improved and further there is no development residue. The pigment dispersion composition for a color filter of the present invention comprises: a coloring pigment; a pigment dispersant; an alkali-soluble resin; and an organic solvent, wherein the pigment dispersant contains an acrylic block polymer containing an amino group and/or a pyridine ring, and the alkali-soluble resin contains a block polymer.
