Patent ID: 8614048

Claim:
A resin having a structural unit derived from a compound represented by the formula (I) wherein R 1 represents a C 1 to C 6 alkyl group that optionally has a halogen atom, a hydrogen atom or a halogen atom; A 1 represents a group represented by the formula (a-1); wherein s represents an integer of 0 to 2; A 10 and A 11 in each occurrence independently represent an optionally substituted C 1 to C 5 aliphatic hydrocarbon group; A 12 represents an optionally substituted C 1 to C 5 aliphatic hydrocarbon group or a single bond; X 10 and X 11 in each occurrence independently represents an oxygen atom, a carbonyl group, a carbonyloxy group or an oxycarbonyl group; provided that a total number of the carbon atom of A 10 , A 11 , A 12 , X 10 and, X 11 is 12 or less; ring X 1 represents a C 2 to C 36 heterocyclic ring, a hydrogen atom contained in the heterocyclic ring may be substituted with a halogen atom, a hydroxy group, a C 1 to C 24 hydrocarbon group, a C 1 to C 12 alkoxy group, a C 2 to C 4 acyl group or a C 2 to C 4 acyloxy group.
