Abstract: The present invention aims to provide a photochromic compound capable of exhibiting photochromic properties regardless of matrix, and the compound is stably dispersed without aggregation in a process of molding (curing) an optical base material. According to the present invention, a polymer photochromic compound, which has a block polymeric group of an oligomeric chain group having relatively favorable compatibility with a solid matrix and an oligomeric chain group having poor compatibility with a solid matrix, forms a nano- to micro-phase separation structure in a solid matrix. The compound does not rely on the solid matrix, its dispersibility is improved and aggregation is prevented or reduced, whereby excellent photochromic properties can be exhibited.
