Abstract:
1. A photosensitive resin composition comprising: an alkali-soluble resin (A); a photopolymerizable compound (B); and a photopolymerization initiator (C), wherein said photopolymerizable compound (B) comprises a polyalkylene glycol di(meth)acrylate having a molecular weight in the range of 500 to 2,000 (B-1) and a compound having a bisphenol skeleton (B-2), an amount of the compound (B-1) to be combined is 30 to 90 parts by weight based on 100 parts by weight of the component (A) solid content, and an amount of the compound (B-2) to be combined is 30 to 90 parts by weight based on 100 parts by weight of the component (A) solid content, wherein said photopolymerization initiator (C) comprises a hexaarylbisimidazole based compound (C1) and an aliphatic multifunctional thiol compound having a plurality of aliphatic thiol groups (C2) as essential components, wherein an amount of the essential component (C2) to be combined is 1 to 10 parts by weight based on 100 parts by weight of the essential component (C1) of said photopolymerization inhibitor (C).
