Patent ID: 8822563

Claim:
A curable resin composition comprising a polymer (A) that has a main chain comprising carbon atoms and a side chain having a polymerizing unsaturated linking group and has a cyclic structure in the main chain and/or the side chain, and a compound having a polymerizing unsaturated group, wherein the polymer (A) has at least one type of recurring unit of the recurring unit represented by the following general formula (1) and the recurring unit represented by the following general formula (2): wherein, in the general formula (1), R 1 represents a hydrogen atom or a substituent; L 1 represents a divalent linking group or a single bond; and the ring α represents a monocyclic or multicyclic ring, wherein, in the general formula (2), the ring β represents a monocyclic or polycyclic ring; and further wherein the recurring unit is selected from the recurring unit represented by the general formula (1) where α contains a cyclic structure having a skeleton with a structure selected from the following group (1), and the recurring unit represented by the general formula (2) where β contains a cyclic structure having a skeleton with a structure selected from the following group (2):
