Document Type and Number:
WIPO Patent Application WO/2018/110429
Kind Code:
A1
Abstract:
Provided is a resin that contains structural units derived from a compound represented by formula (I') and structural units having an acid-labile group. (In the formula, R1 and R2 each independently denote an alkyl group that may have a halogen atom, a hydrogen atom or a halogen atom. Ar denotes an optionally substituted aromatic hydrocarbon group. L1 denotes a group represented by formula (X1-1) or the like. L11, L13, L15 and L17 each independently denote an alkane diyl group. L12, L14, L16 and L18 each independently denote -O-, -CO-, -CO-O-, -O-CO- or -O-CO-O-. * and ** denote bonds, and ** denotes a bond to an iodine atom.)
