Abstract
A curable composition comprising (1) 0.1 to 20 parts by weight of a silicon compound having a silanol group or a functional group for forming a silanol group upon hydrolysis and no radically polymerizable group, such as γ-glycidoxypropyltrimethoxysilane, (2) 100 parts by weight of radically polymerizable monomers and (3) 0.01 to 20 parts by weight of a photochromic compound, wherein This curable composition is capable of forming a photochromic coating layer which shows excellent photochromic properties such as high color development density and fast fading rate, is free from the dissolution of the photochromic compound, exhibits high adhesion to a substrate through a simple pre-treatment and has excellent hard coating applicability.
