Title:
COATING COMPOSITION AND OPTICAL ARTICLE
Document Type and Number:
WIPO Patent Application WO/2004/050775
Kind Code:
A1
Abstract:
A coating composition which, when applied to a substrate such as a plastic lens, can form on the substrate surface a photochromic coating layer having satisfactory photochromism and excellent adhesion to the substrate. The composition contains as monomer ingredients, for example, 0.1 to 20 wt.% monomer having a group which generates a silanol group upon hydrolysis, such as &gammad -methacryloyloxypropyltrimethoxysilane and 0.1 to 50 wt.% monomer having at least one oxycarbonyl group per molecule. A maleimide compound may be further contained as other monomer ingredient. More desirably, the composition contains an amine compound.
