Also disclosed is a pigment-dispersed composition containing (A) a graft high-molecular polymer in which acrylic acid is copolymerized at a proportion of from 5% by mass to 30% by mass in the main chain thereof, (B) a pigment, and (C) an organic solvent. 

Pigment-dispersed composition, colored photosensitive composition, photocurable composition, color filter, liquid crystal display device, and solid-state image pickup device

Provided are a processed pigment excellent in dispersibility and dispersion stability, a pigment-dispersed composition excellent in dispersibility and dispersion stability of a pigment that uses the processed pigment, a colored photosensitive composition using the pigment-dispersed composition, and a color filter having improved color properties that uses the colored photosensitive composition, in which a pigment is covered with at least one of a specific polymer compound selected from the following (SP-1) to (SP-3); wherein, R, R, Aand Prespectively represent an organic linkage group, a single bond or a divalent organic linkage group, a monovalent organic group containing such as an organic dye structure, and a polymer skeleton.

Processed pigment, pigment-dispersed composition, colored photosensitive composition, color filter, liquid crystal display element, and solid image pickup element

The present invention provides: a pigment dispersion composition including (A) an organic pigment, (B) a pigment derivative represented by Formula (I) below and (C) a polymer compound having a pigment-adsorptive functional group; a curable color composition including the pigment dispersion composition, a polymerizable compound and a polymerization initiator; and a color filter having a color region formed using the curable color composition and a method for producing the same. Q represents an organic colorant residue; A represents an ethylene group or the like; and R represents a hydroxyl group or a group represented by &#x2014;NH-A-Z; Z represents &#x2014;SOH, &#x2014;COOH or a salt thereof; and n represents an integer of from 1 to 4. When R represents &#x2014;NH-A-Z, the structures represented by the two &#x2014;NH-A-Zs bonded to the triazine ring contained in each of the n partial structures bonded to Q may be the same as each other or different from each other.
