PHOTOSENSITIVE COLOR RESIN COMPOSITION FOR COLOR FILTER, COLOR FILTER, LIQUID CRYSTAL DISPLAY, AND ORGANIC EL DISPLAY

摘要

Disclosed is a photosensitive color resin composition for color filters, which is excellent in image-forming property even when a colorant has a high concentration, while having an excellent balance between sensitivity and solubility. This photosensitive color resin composition for color filters is also excellent in sharpness of a pixel edge and adhesion. Specifically disclosed is a photosensitive color resin composition for color filters, which contains an alkali-soluble resin (A) obtained by reacting a reaction product of an epoxy resin (a) represented by the general formula (1-a) below and an unsaturated group-containing carboxylic acid (b) with a polybasic acid and/or an anhydride thereof (c), a photopolymerization initiator (B), and a colorant (C). The alkali-soluble resin (A) has a weight average molecular weight of not less than 3,300 but not more than 50,000. (1-a) (In the formula, n represents an average value which is a number of 0-10; R41 represents a hydrogen atom, a halogen atom, an alkyl group having 1-8 carbon atoms, a cycloalkyl group having 3-10 carbon atoms, a phenyl group, a naphthyl group or a biphenyl group; and G represents a glycidyl group.)
