Patent ID: 8129086

Claim:
A polymerizable compound represented by the following general formula (1): wherein, each of R 1 and R 2 independently represents any of a hydrogen atom or a linear, a branched, or a cyclic alkyl group having 1 to 6 carbon atoms; R 3 represents a methylene group or an ethylene group; R 4 represents any of a hydrogen atom, an alkyl group having 1 to 30 carbon atoms, an alkyl group a part of or all of whose hydrogen atoms are substituted by a halogen atom, an alkoxy group, an alkanoyl group, an alkoxycarbonyl group, an aryl group having 6 to 10 carbon atoms, a halogen atom, or a cyano group; R 5 represents a hydrogen atom or a methyl group; X represents any of a single bond, —C(═O)—O—R 6 —, a phenylene group, or a naphthylene group; and R 6 represents any of a linear, a branched, or a cyclic alkylene group having 1 to 10 carbon atoms, and optionally containing an ester group, an ether group, or a lactone ring.
