COATING COMPOSITION AND OPTICAL ARTICLE

摘要

There is provided a coating composition which can be applied to a substrate such as a plastic lens so as to form a photochromic coating layer having good photochromic properties and excellent adhesion to the substrate on the surface of the substrate. <??>This composition comprises, for example, as monomer components, 0.1 to 20 wt% of monomer having a group which produces a silanol group through hydrolysis such as gamma -methacryloyloxypropyltrimethoxysilane and 0.1 to 50 wt% of monomer having at least one oxycarbonyl group in a molecule. The composition can further contain a maleimide compound as a monomer component and further desirably contains an amine compound.
