Abstract:
Vinylphenylpropionic acid derivatives represented by the following formula (1): wherein R1 is a hydrogen atom or a methyl group, R2 is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms which may be substituted or a phenyl group which may be substituted, R3 is a hydrogen atom or a phenyl group which may be substituted and Z1 is a group represented by the following formula (2): wherein R4 and R5 may be the same or different and each is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms which may be substituted or a phenyl group which may be substituted, and R6 is an alkyl group having 1 to 8 carbon atoms which may be substituted or a phenyl group which may be substituted, or any two of R4, R5 and R6 may be bonded together with a carbon atom bonded thereto to form a cyclic aliphatic group, or a group represented by the following formula (3): wherein R7 and R8 may be the same or different and each a hydrogen atom, an alkyl group having 1 to 8 carbon atoms which may be substituted or a phenyl group which may be substituted, R9 is an alkyl group having 1 to 8 carbon atoms which may be substituted or a phenyl group which may be substituted, or any two of R7, R8 and R9 may be bonded together with a carbon atom bonded thereto to form a cyclic aliphatic group, with proviso that the group represented by is an acid dissociable group which generates a carboxyl group (â€”COOH) in the presence of an acid.
