• wherein Q1 and Q2 are each independently at least one selected from the group consisting of an alkyl group, an aryl group, an arylalkyl group and a halogenated alkyl group, X is each independently at least one selected from the group consisting of —O—, —C(═O)—, —C(═O)O— and —C(═O)NH—, m and n are each independently an integer of 0 to 2, and 1 is an integer of 0 or 1,
• if P2 is plural, P2 each may be the same or different and p is a positive integer, and has a structure unit represented by formula (3):
• wherein P3 and P4 are each independently a monovalent aliphatic hydrocarbon group of 1 to 5 carbon atoms or a monovalent aromatic group of 6 to 10 carbon atoms, if P3 is plural, P3 each may be the same or different, if P4 is plural, P4 each may be the same or different and q is a positive integer, and
• the resin composition comprises a compound represented by formula (4):
