Abstract:
1. A curable resin composition for forming a photosensitive pattern comprising: a copolymer (a) having a polymer chain including at least a repeating unit having an acidic functional group and a repeating unit including a photocurable functional group; a photopolymerization initiator (b) having a tertiary amine structure; and a photocurable compound (c) having at least one acidic functional group and at least three photocurable functional groups wherein the photocurable functional groups are photoradical polymerizing functional groups; wherein the curable resin composition may contain a photocurable compound (d) having at least two photocurable functional groups with the proviso that the photocurable compound (d) is other than the photocurable compound (c); wherein the copolymer (a) is an imide group containing polymer (a wherein each of R8 and R9 is an alkyl group having 4 or less carbon atoms independently, or one of R8 and R9 is a hydrogen atom and the other is an alkyl group having 4 or less carbon atoms, or both R8 and R9 together form a carbon ring; wherein a content of conolymer (a wherein a solid content weight ratio ((a
