Claim:
A photosensitive composition comprising: a) a triazine-based photoactive compound containing oxime ester represented by the following formula (1); b) a polymerizable compound having an ethylenically unsaturated bond, c) an alkali-soluble resin binder; and d) a solvent. wherein n is an integer of 1 or 2; when n=1, R is selected from the group consisting of a C 1 to C 6 alkyl group, a C 1 to C 6 haloalkyl group, a C 1 to C 6 alkyl group substituted with at least one group selected from the group consisting of NL 2 , OL and SL wherein L is a hydrogen atom or C 1 to C 6 alkyl group, a phenyl group unsubstituted or substituted with at least one group selected from the group consisting of a C 1 to C 6 alkyl group, a halogen atom, a nitrile group, OH and COOH, and a C 2 to C 5 alkylcarboxyl group; when n=2, R is selected from the group consisting of a C 2 to C 6 alkylene group, a 1,2-phenylene group, a 1,3-phenylene group, a 1,4-phenylene group, R′ is selected from the group consisting of a hydrogen atom, a C 1 to C 6 alkyl group, a nitrile group and a phenyl group; X is a C 5 to C 20 arylene group unsubstituted or substituted with at least one group selected from the group consisting of a halogen atom, CN, a C 1 to C 6 alkyl group, a C 1 to C 6 alkoxy group, a C 1 to C 6 alkylthio group and a morpholino group; a divalent C 4 to C 20 heterocyclic group containing O, N or S, unsubstituted or substituted with at least one group selected from the group consisting of a halogen atom, CN, a C 1 to C 6 alkyl group, a C 1 to C 6 alkoxy group, a C 1 to C 6 alkylthio group and a morpholino group; or a compound of the following formula (2): wherein Z and Z′ are each independently one selected from the group consisting of CH 2 , O, S, NR″ wherein R″ is a hydrogen atom or C 1 to C 6 alkyl group, and CH═CH; l and m are an integer of 0 to 2, provided that l+m is not 0; A is a simple linkage, or one selected from the group consisting of C p H 2p , O(CH 2 O) p , CH═CH, NR′″, S, O, S═O, SO 2 , and C═O wherein p is an integer of 1 to 6 and R′″ is a hydrogen atom or C 1 to C 6 alkyl group, provided that A is not a simple linkage when l+m=1; and Y and Y′ are each optionally selected from the group consisting of a hydrogen atom, a halogen atom, CN, a C 1 to C 6 alkyl group, a C 1 to C 6 alkoxy group, a C 1 to C 6 alkylthio group and a morpholino group.
