Abstract:
Provided is a polyfunctional compound which can be used as an optical recording material in which a large quantity of information data can be recorded optically at a high density, which can be used as an optical waveguide material using a refractive index difference occurring between a light-irradiated part and a part not irradiated with light, and which is capable of forming a film and can be used as a photo-alignment film material having excellent photosensitivity.
