Claim:
1. A photoresist composition, comprising: 10-60 weight parts of a polymer dye; 10-60 weight parts of an alkali soluble resin; 5-50 weight parts of a multi-functional monomer; 0.5-10 weight parts of a photo initiator; 100-450 weight parts of an organic solvent; and 0-5 weight parts of an auxiliary agent; wherein the polymer dye is formed by the copolymerization of an acrylated dye represented by General Formula I and an acrylic acid or acrylate represented by General Formula II: wherein, in General Formula I, Dye represents a residue of a dye selected from the group consisting of Disperse Red 1, Acid Red 14, Acid Red 20, Acid Red 33, Acid Red 35, Acid Red 337, Acid Yellow 9, Acid Red 17, Acid Green 10, Acid Blue 7, Acid Blue 9, Acid Blue 62, Acid Blue 120, Acid Purple 43, Acid Purple 49, Acid Orange 24, Acid Black 1, Solvent Purple 3, Solvent Purple 13, and Solvent Purple 14; and R wherein the mole numbers of the acrylated dye represented by General Formula I and of the acrylic acid or acrylate represented by General Formula II are x and y, respectively, and x:y =1:0.05-10; and wherein the weight average molecular weight of the polymer dye is 2000-50000.
