Abstract
Provided is an easy method for production of a high-performance polyfunctional compound which can be used as an optical recording material, an optical waveguide material, a photo-alignment film material, or the like, in a simple manner. The method for production of a polyfunctional compound includes conducting a Michael addition of a compound (A) having a hydrogen atom of pKa≦15 to a (meth)acrylate or a (meth)acrylamide (B), in which at least one of the compounds (A) and (B) has a photoisomerization group and/or a liquid-crystalline group.
