ABSTRACT:
A compound including an epoxy group that has a heat curing property and a chalcone group that has a radiation curing property is represented by the following formula:wherein n is an integer from 1 to 10,000, and each of R1, R2, R3, R4, R5, R6, R7and R8is selected from a group consisting of a hydrogen atom, alkyl group, alkoxy group, halogen atom and nitro group. The compound has a high curing efficiency. A photoresist composition including the compound above substantially prevents the formation of remnant in a photoresist pattern used in the manufacturing of a color filter. In addition, the color filter pattern that is formed using the photoresist composition has high color reproductivity and brightness.
