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. A carbonyl compound is useful as a raw material for producing the polymerizable compound. (In the formula (I), Yto Yrepresent —C(═O)—O—, Gand Grepresent a Cdivalent linear aliphatic group, Zand Zrepresent a Calkenyl group that is unsubstituted, or substituted with a halogen atom, Arepresents a Corganic group with at least one aromatic ring, Arepresents a hydrogen atom or Calkyl group, Arepresents a trivalent aromatic group, Aand Arepresent a Cdivalent alicyclic hydrocarbon group, Aand Arepresent a Cdivalent aromatic group or the like, and Qrepresents a hydrogen atom.)
