摘要： A compound of the following formula (1): CH2═CR1—COO—R2—OCO-Cy-COO-Cy-A-Cy-R3  (1) wherein R1 is a hydrogen atom or a methyl group; R2 is a hydrocarbon group having from 1 to 8 carbon atoms, provided that some or all of hydrogen atoms bonded to carbon atoms in the group may be substituted by fluorine atoms, and when it has 2 or more carbon atoms, it may have an etheric oxygen atom in a carbon-carbon bond, R3 is an alkyl or alkoxy group having from 1 to 8 carbon atoms, or a fluorine atom, provided that when it is the alkyl or alkoxy group, some or all of hydrogen atoms bonded to carbon atoms in the group may be substituted by fluorine atoms; Cy is a trans-1,4-cyclohexylene group, provided that hydrogen atoms bonded to carbon atoms in the group may independently be substituted by fluorine atoms, chlorine atoms or methyl groups; and A is a single bond, a trans-1,4-cyclohexylene group or a 1,4-phenylene group, provided that hydrogen atoms bonded to carbon atoms in the group may independently be substituted by fluorine atoms, chlorine atoms or methyl groups.
