Patent ID: 8765357

Claim:
A resin comprising a structural unit derived from a compound represented by the formula (I): wherein R 1 represents a hydrogen atom or a methyl group, A 2 represents a divalent fluorine-containing C1-C12 hydrocarbon group, and A 1 represents a group represented by the formula (a-g1): A 10 -X 10 s A 11 - (a-g1) wherein A 10 is independently in each occurrence a C1-C5 aliphatic hydrocarbon group, A 11 represents a C1-C5 aliphatic hydrocarbon group, X 10 is independently in each occurrence —O—, —CO—, —CO—O— or —O—CO—, and s represents an integer of 0 to 2; and a structural unit derived from a monomer having no acid-labile group and having one or more fluorine atoms.
