Abstract

The polymerizable compound has a hydrazone moiety. The present invention also provides a polymerizable composition in which discoloration and reduction of aligning property do not easily occur. Furthermore, the present invention provides a polymer obtained by polymerizing a polymerizable composition containing a compound obtained by the production method and an optically anisotropic body using the polymer. The present invention provides a method for producing a polymerizable compound including a step of reacting a compound represented by General Formula (I-B-a) with a compound represented by General Formula (I-B-b) to obtain a compound represented by General Formula (I-C), and provides a composition which contains a compound obtained by this production method.
