Patent ID: 8784684

Claim:
A compound which has a benzoxazinone ring and an aromatic ring that directly bonds to the benzoxazinone ring, and has a mesogenic core substituted by a substituent having a polymerizable functional group, which is represented by the following formula (I): wherein each of R 1 and R 2 independently represents a hydrogen atom, a halogen, NO 2 , CN, NCS, a linear, branched or cyclic alkyl group having 1 to 12 carbon atoms (here, among —CH 2 — that configure the alkyl group, one —CH 2 — or two or more non-adjacent —CH 2 — may be substituted by —O—, —S—, —CO—, —COO—, —OCO—, —OCOO—, —CH═CH—, —C≡C—, —CONR 3 —, —NR 3 CO— or —NR 3 —) or P-Sp-L-, and at least one of R 1 and R 2 is P-Sp-L-; P represents a polymerizable functional group; Sp represents a single bond or an alkylene group having 1 to 12 carbon atoms (here, among non-terminal —CH 2 — that configure the alkylene group, one non-terminal —CH 2 — or two or more non-adjacent non-terminal —CH 2 — may be substituted by —O—, —S—, —CO—, —COO—, —OCO—, —CH═CH—, —C≡C—, —CONR 4 —, —NR 4 CO— or —NR 4 —); L represents —O—, —S—, —CO—, —COO—, —OCO—, —OCOO—, —CONR 5 —, —NR 5 CO—, —NR 5 — or a single bond; when Sp is a single bond, L is also a single bond; each of A 1 and A 2 independently represents a 1,4-phenylene group; one or two or more hydrogen atoms in the 1,4-phenylene group may be substituted by an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an alkoxycarbonyl group having 2 to 5 carbon atoms, an acyloxy group having 2 to 5 carbon atoms, an acyl group having 2 to 4 carbon atoms, an amide group having 2 to 5 carbon atoms, a cyano group or a halogen atom; each of Z 1 and Z 2 independently represents —COO—, —OCO—, —CONR 6 —, —NR 6 CO—, —OCH 2 —, —CH 2 O—, —CH 2 S—, —SCH 2 —, —CH 2 CH 2 — or a single bond; each of X 1 , X 2 , X 3 , X 4 , X 5 , X 6 and X 7 independently represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an alkoxycarbonyl group having 2 to 5 carbon atoms, an acyloxy group having 2 to 5 carbon atoms, an acyl group having 2 to 4 carbon atoms, an amide group having 2 to 5 carbon atoms, a cyano group or a halogen atom; each of R 3 , R 4 , R 5 and R 6 independently represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; each of m and n independently represents 0, 1 or 2, and m+n=1 or 2.
