The purpose of the present invention is to provide a photochromic compound which can exhibit photochromic properties independent of a substrate and which is stably dispersed without aggregation during an optical substrate molding process (curing process). According to the present invention, by means of a polymer photochromic compound having an oligomer chain group having a comparatively excellent compatibility with a solid substrate and a block polymer-like group of an oligomer chain group having a poor compatibility with the solid substrate, a phase-separated structure in the nanometer to micrometer order is formed in the solid substrate. As a result, it is possible to improve dispersibility and suppress aggregation without depending on a solid substrate, and as a result, it is possible to exhibit a high degree of photochromic properties. 本发明的目的在于提供一种光致变色化合物，其能不依赖于基质而表现出光致变色特性，在光学基材成形过程(固化过程)中，稳定地分散存在而不发生聚集。根据本发明，通过具有与固体基质的相容性比较优异的低聚物链基、和与固体基质的相容性差的低聚物链基的嵌段聚合物状的基团的高分子光致变色化合物，由此在固体基质中形成纳米至微米级的相分离结构，能够不依赖于固体基质
