Abstract
A photosensitive resin composition includes a binder polymer, a photopolymerizable compound, and a photopolymerization initiator. The binder polymer has a structural unit derived from a (meth)acrylic acid, a structural unit derived from styrene or α-methylstyrene, and a structural unit derived from a hydroxyalkyl (meth)acrylate ester having a hydroxyalkyl group having from 1 to 12 carbon atoms. The photopolymerizable compound include a bisphenolic di(meth)acrylate having from 1 to 20 structural units of an ethyleneoxy group and having from 0 to 7 structural units of a propyleneoxy group.
