Patent ID: 8354219

Claim:
A photosensitive resin composition comprising: (A) a polyamic acid comprising a polymer of at least one diamine compound comprising a compound of Chemical Formula (1) as follows and at least one acid dianhydride; (B) a photopolymerizable compound having at least one polymerizable ethylenic unsaturated bond in its molecule; and (C) a photoinitiator: in Chemical Formula (1), each of X 1 to X 4 is independently —O— or NR′, in which each R′ is independently hydrogen or an alkyl group of C1 to C3; R 1 is a tetravalent cycloaliphatic hydrocarbon group of C5 to C18 or a tetravalent aromatic hydrocarbon group of C6 to C18; each of R 2 and R 3 is independently an alkylene group of C1 to C6; each of R 4 and R 5 is independently hydrogen or an alkyl group of C1 to C6; and each of Ar 1 and Ar 2 is independently an arylene group of C6 to C18.
