Coloring resin composition, coloring film, black matrix, color filter and organic EL display device

Abstract

The objective of this invention is to provide a coloring resin composition that reduces the reflectivity of a colored film surface and maintains the low reflectivity of the colored film even after prolonged alkaline development treatment. The solution is a coloring resin composition containing (A) a colorant, (B) an alkali-soluble resin, (C) hollow silicon dioxide particles, and as other components (D1) a photopolymerization initiator having two or more oxime ester groups in one molecule or (D2) a photopolymerization initiator having one oxime ester group in one molecule and (E) a thiol compound.
