| 摘要 |
A novel monomer compound having a lactone moiety of the present invention can be converted into polymers usable as resist materials with excellent properties, etc., and an alcohol compound having a lactone moiety of the invention is useful as a material for the monomer compound. The compounds are represented by the following general formula [1]: wherein one of R<1 >and R<2 >represents a hydrogen atom, an acryloyl group, or a methacryloyl group, and the other represents an alkyl group; R<3 >and R<4 >independently represent a hydrogen atom or an alkyl group; R<5 >and R<6 >both represent a hydrogen atom or are combined to form a methylene chain that may have an alkyl group; and R<7 >and R<8 >independently represent a hydrogen atom or a methyl group.
