The present invention is a polymerizable compound (I), a polymerizable composition containing the polymerizable compound and a polymerization initiator, a polymer obtained by polymerizing the above polymerizable compound or polymerizable composition, and a polymer comprising the polymer as a constituent material. Optically anisotropic body, carbonyl compound (4), method for producing polymerizable compound (I) characterized by reacting the compound with hydrazine compound (6), and production using carbonyl compound (4) as polymerizable compound (I) raw material method. According to the present invention, it is possible to provide a polymerizable compound that can obtain an optical film that has a practically low melting point, is excellent in solubility in a general-purpose solvent, can be produced at low cost, and can perform uniform polarization conversion over a wide wavelength range, and Carbonyl compounds and the like useful as raw materials for their production. In formula (I), Y 1 to Y 8 represent -C(=O)-O-, etc., G 1 and G 2 represent divalent chain aliphatic groups with 1 to 20 carbon atoms, etc. Z 1 , Z 2 represents an alkenyl group with 2 to 10 carbon atoms that is unsubstituted or substituted with a halogen atom, A x represents an organic group with an aromatic ring with 2 to 30 carbon atoms, A y represents a hydrogen atom, and the number of carbon atoms is 1~20 alkyl group, etc., A 1 means trivalent aromatic group, etc., A 2 , A 3 means divalent alicyclic hydrocarbon group with 3~30 carbon atoms, etc., A 4 , A 5 means carbon number is 6~30 divalent aromatic groups, etc., Q1 represents a hydrogen atom, etc. |
