Photosensitive resin composition for color filters and uses thereof

A photosensitive resin composition for a color filter, comprising:

• an alkali-soluble resin (A-1) formed by copolymerizing an ethylenically unsaturated monomer (a-1) having a carboxylic acid group, a compound (a-2) having a cyclicimide group represented by formula (1), and other copolymerizable ethylenically unsaturated monomers (a-3) except for the ethylenically unsaturated monomer (a-1) having a carboxylic acid group and the compound (a-2) having a cyclicimide group represented by formula (1),
• in formula (1), R1 and R2 are each independently selected from the group consisting of a hydrogen atom and an alkyl group of a carbon number of 1 to 10, but R1 and R2 are not both a hydrogen atom;
• or R1 and R2 both form a carbocyclic ring,
• wherein based on a total amount of 100 parts by weight of the ethylenically unsaturated monomer (a-1) having a carboxylic acid group, the compound (a-2) having a cyclicimide group represented by formula (1), and the other copolymerizable ethylenically unsaturated monomers (a-3), a content of the compound (a-2) having a cyclicimide group represented by formula (1) is between 20 parts by weight and 60 parts by weight;
• an alkali-soluble resin (A-2) having a functional group represented by formula (2),
• in formula (2), each R3 is independently selected from the group consisting of a hydrogen atom, a straight chain or branch chain alkyl group of a carbon number of 1 to 5, a phenyl group, or a halogen atom;
• a compound (B) having an ethylenically unsaturated group;
• a photoinitiator (C);
• an organic solvent (D);
• and
• a pigment (E).
