Patent ID: 8420854

Claim:
A di(meth)acrylate compound represented by the following formula (1): CH 2 ═CR 1 —COO—(K) m -E 1 -E 2 -(E 3 ) f -(L) n -OCO—CR 2 ═CH 2 (1) wherein R 1 and R 2 are each independently a hydrogen atom or a methyl group, m and n are each independently 0 or 1, K is —(CH 2 ) p COO—, —(CH 2 ) p OCO—, —(CH 2 ) p O—, or —(CH 2 ) p — (where each p is independently an integer of 1 to 8), wherein an ethereal oxygen atom may be present in a carbon to carbon bond and some or all of hydrogen atoms may be each substituted by a fluorine atom, L is —OCO(CH 2 ) q —, —COO(CH 2 ) q —, —O(CH 2 ) q —, or —(CH 2 ) q — (where each q is independently an integer of 1 to 8), wherein an ethereal oxygen atom may be present in a carbon to carbon bond and some or all of hydrogen atoms may be each substituted by a fluorine atom, E 1 is a trans-2,6-decahydronaphthalene group and E 2 is a trans-1,4-cyclohexylene group (where, in the trans-1,4-cyclohexylene group in E 2 and trans-2,6-decahydronaphthalene group in E 1 , some or all of hydrogen atoms bonded to carbon atoms in these groups may be each substituted by a fluorine atom or a methyl group), E 3 is a trans-1,4-cyclohexylene group or a 1,4-phenylene group (where, in the trans-1,4-cyclohexylene group and 1,4-phenylene group in E 3 , some or all of hydrogen atoms bonded to carbon atoms in these groups may be each substituted by a fluorine atom or a methyl group), and f is 0 or 1.
