The present invention relates to: a hydrazine compound represented by formula (3), wherein Ax and Ay have the meanings indicated in claims 1 to 5; a method for producing an optically anisotropic article by (i) obtaining a polymerizable compound by reacting the hydrazine compound with a carbonyl compound, (ii) forming an alignment film on a substrate, and (iii) forming a liquid crystal layer on the alignment film using the polymer obtained by polymerizing the polymerizable compound or a polymerizable composition including the polymerizable compound and an initiator; and a method for producing a polymerizable compound represented by formula (I), by reacting the hydrazine compound with a carbonyl compound represented by formula (4). The film thus obtained has a low melting point, excellent solubility, is capable of being manufactured at low cost, and capable of uniform polarized light conversion across a broad wavelength region.
