Abstract: PURPOSE: Provided are a photo-crosslinking polymer, which ensures excellent thermostability and photostability and has good color implementability, increased productivity and reduced production cost, and a color filter using the above polymer. CONSTITUTION: The photo-crosslinking polymer is represented by formula 1, wherein n is an integer of 1-10000, and X is a compound of formula 5, 6 or 7(in which, each of R1-R10 is independently or simultaneously a hydrogen atom, a halogen atom, a nitro group, an alkyl or alkoxy group having 1-10 of carbon atoms); and is prepared by the method comprising the steps of: protecting bishydroxy phenylvaleric acid with acetic anhydride; esterifying the resultant with a photochromic spiropyran derivative of formula 2, 3 or 4; deprotecting the resultant with a base; and reacting the resultant with epichlorohydrin in the presence of sodium hydroxide. The color filter is prepared by using the above photo-crosslinking polymer.
