Abstract

A polymerizable compound has a practical low melting point, excellent solubility in a general-purpose solvent, and can produce an optical film at low cost, exhibits low reflected luminance, and achieves uniform conversion of polarized light over a wide wavelength band, an optically anisotropic article.

First claim

1 . A carbonyl compound represented by a formula (4),

wherein Y 1 to Y 8 are independently a chemical single bond, —O—, —S—, —O—C(═O)—, —C(═O)—O—, —O—C(═O)—O—, —NR 1 —C(═O)—, —C(═O)—NR 1 —, —O—C(═O)—NR 1 —, —NR 1 —C(═O)—O—, —NR 1 —C(═O)—NR 1 —, —O—NR 1 —, or —NR 1 —O—, R 1 is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms,
G 1 and G 2 are independently a substituted or unsubstituted divalent linear aliphatic group having 1 to 20 carbon atoms that optionally includes —O—, —S—, —O—C(═O)—, —C(═O)—O—, —O—C(═O)—O—, —NR 2 —C(═O)—, —C(═O)—NR 2 —, —NR 2 —, or —C(═O)—, provided that a case where the aliphatic group includes two or more contiguous —O— or —S— is excluded, R 2 is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms,
Z 1 and Z 2 are independently an alkenyl group having 2 to 10 carbon atoms that is unsubstituted, or substituted with a halogen atom,
A 1 is a substituted or unsubstituted trivalent aromatic group,
A 2 and A 3 are independently a substituted or unsubstituted divalent alicyclic hydrocarbon group having 3 to 30 carbon atoms,
A 4 and A 5 are independently a substituted or unsubstituted divalent aromatic group having 6 to 30 carbon atoms, and
Q 1 is a hydrogen atom, or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms.

2 . The carbonyl compound according to claim 1 , wherein A 1 is a substituted or unsubstituted trivalent benzene ring group, or a substituted or unsubstituted trivalent naphthalene ring group.

3 . The carbonyl compound according to claim 1 , wherein A 2 and A 3 are independently a substituted or unsubstituted divalent cyclohexyl group.

4 . The carbonyl compound according to claim 1 , wherein Z 1 and Z 2 are independently CH 2 ═CH—, CH 2 ═C(CH 3 )—, or CH 2 ═C(Cl)—.

5 . A hydrazine compound represented by any one of formulae (E), (M), (Q), (S), (U), (V), (Y), (Z), (E1), (G1), (L1), (O1), (P1), (Y1), (Z1), (A2), (B2), (C2), (D2), (E2), (F2), (H2), (I2), (J2), (R2), (S2), (T2), (U2), and (V2):
