COLORING RESIN COMPOSITION FOR COLOR FILTER SUBSTRATE, METHOD FOR MANUFACTURING COLOR FILTER SUBSTRATE AND COLOR FILTER SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a coloring resin composition for manufacturing a color filter substrate with improved water and moisture resistance and excellent color characteristics. SOLUTION: A water soluble vinyl type resin is a copolymer composed of at least a vinyl type monomer (A) expressed by the general formula (I), a vinyl type monomer with a carboxyl group (B) and a vinyl type monomer with a hydroxyl group (C). Ink for the color filter substrate is characterized by having a weight ratio of the monomer A to the monomer B to be A:B=1:0.8-8, a weight ratio of the monomer A to the monomer C to be A:C=1:0.8-10 and the total sum of three components, i.e., the monomers A, B, C, is equal to or more than 80 wt.% in the water soluble vinyl type resin.
