Abstract:
1. A photoreactive acrylate polymer comprising a repeating unit of the following formula 3: wherein m is 50 to 5,000; R1 is hydrogen or substituted or unsubstituted alkyl having 1 to 3 carbon atoms; R2 is a chemical bond or a substituted or unsubstituted linear or branched alkylene radical having 1 to 20 carbon atoms; and R3 is at least one radical bonded to R2 and represented by the following formula 1a: wherein A is chemical bond, oxygen, sulfur, or —NH—; B is selected from the group consisting of chemical bond, substituted or unsubstituted alkylene having 1 to 20 carbon atoms, carbonyl, —C(═O)O—, —O—C(═O)—, substituted or unsubstituted arylene having 6 to 40 carbon atoms, and substituted or unsubstituted heteroarylene having 6 to 40 carbon atoms; R9 is selected from the group consisting of chemical bond, substituted or unsubstituted alkylene having 1 to 20 carbon atoms, substituted or unsubstituted alkenylene having 2 to 20 carbon atoms, substituted or unsubstituted cycloalkylene having 3 to 12 carbon atoms, substituted or unsubstituted arylene having 6 to 40 carbon atoms, substituted or unsubstituted aralkylene having 7 to 15 carbon atoms, and substituted or unsubstituted alkynylene having 2 to 20 carbon atoms; and at least one of R10 to R14 is a radical represented by -L-R15-R16-(substituted or unsubstituted aryl having 6 to 40 carbon atoms), wherein among the R10 to R14, the remainders other than the radical of -L-R15-R16-(substituted or unsubstituted aryl having 6 to 40 carbon atoms) are the same as or different from one another and independently selected from the group consisting of hydrogen, halogen, substituted or unsubstituted alkyl having 1 to 20 carbon atoms, substituted or unsubstituted alkoxy having 1 to 20 carbon atoms, substituted or unsubstituted aryloxy having 6 to 30 carbon atoms, substituted or unsubstituted aryl having 6 to 40 carbon atoms, and heteroaryl having 6 to 40 carbon atoms with hetero elements in Group 14, 15 or 16; L is selected from the group consisting of oxygen, sulfur, —NH—, substituted or unsubstituted alkylene having 1 to 20 carbon atoms, carbonyl, —C(═O)O—, —O—C(═O)—, —CONH—, and substituted or unsubstituted arylene having 6 to 40 carbon atoms; R15 is substituted or unsubstituted alkylene having 1 to 10 carbon atoms; and R16 is selected from the group consisting of chemical bond, —O—, —C(═O)O—, —OC(═O)—, —NH—, —S—, and —C(═O)—.
