Abstract:
A photochromic curable composition comprising, as radically polymerizable component (A), a silsesquioxane component (A1) having a radically polymerizable group and a bifunctional radically polymerizable monomer (A2) represented by the following general formula (1), wherein a is a number of 0 to 30, and b is a number of 0 to 30 on condition that an average value of a+b is 2 to 30, R1, R2, R3 and R4 are each a hydrogen atom or a methyl group, and A is a divalent organic group on condition that the number of carbon atoms is 1 to 20, and a photochromic compound (B).
