<p>There is provided a photosensitive resin composition comprising: a copolymer resin; a bifunctional or higher polyfunctional photopolymerizable acrylate monomer; an epoxy resin; and an initiator, the copolymer resin comprising 5 to 55% by mole of constituent units represented by formula (1) and 5 to 95% by mole at constituent units represented by formula (2), the constituent units represented by formula (1) having been partially reacted, through carboxyl groups thereof, with a (meth)acryloylalkyl isocyanate compound, the constituent units represented by formula (2) having been partially reacted, through hydroxyl groups thereof, with a (meth)acryloylalkyl isocyanate compound, the copolymer resin containing 5 to 95% by mole of (meth)acryloyl groups and having an acid value of 5 to 400 mg KOH/g and a weight average molecular weight of 10,000 to 1,000,000 as determined using polystyrene as a standard: <CHEM> wherein R represents hydrogen or an alkyl group having 1 to 5 carbon atoms and R1 represents an alkylene group having 2 to 4 carbon atoms. There is further provided a color filter comprising: a transparent substrate; a colored layer provided on the transparent substrate; and a protective layer provided so as to cover the colored layer, the protective layer having been formed by coating a photosensitive resin composition, exposing the coating, developing the exposed coating with an alkali, and heating the developed coating, the photosensitive resin composition comprising: a copolymer resin; a bifunctional or higher polyfunctional photopolymerizable acrylate monomer; an epoxy resin; and an initiator, said copolymer resin comprising 5 to 55% by mole of constituent units represented by formula (1) and 5 to 95% by mole of constituent units represented by formula (2), the constituent units represented by formula (1) having been partially reacted, through carboxyl groups thereof, with a (meth)acryloylalkyl isocyanate compound, the constituent units represented by formula (2) having been partially reacted, through hydroxyl groups thereof, with a (meth)acryloylalkyl isocyanate compound, said copolymer resin containing 5 to 95% by mole of (meth)acryloyl groups and having an acid value of 5 to 400 mg KOH/g and a weight average molecular weight of 10,000 to 1,000,000 as determined using polystyrene as a standard. <IMAGE></p> |
