PROBLEM TO BE SOLVED: To provide a photosensitive resin composition for a color filter having a high color purity and a high sensitivity with less heat yellowing in a region containing a high concentration colorant. As an essential component, component (A); a reaction product of an epoxy compound having two glycidyl ether groups derived from bisphenols and (meth) acrylic acid is further added with a polybasic carboxylic acid or an anhydride thereof. Unsaturated group-containing alkali-soluble resin obtained by reaction, component (B); photopolymerizable monomer having one or more ethylenically unsaturated bonds, component (C); compound having one or more epoxy groups, (D ) Component: photopolymerization initiators containing a compound represented by the general formula (I), and (E) component: a colorant containing one or more organic pigments as essential components, based on the total weight (R) of the resin components A photosensitive resin composition for a color filter, wherein the ratio (E) / (R) of (E) is 0.5 to 2.5.
