Coating composition for optical plastic moldings. |
摘要 |
<p>A coating composition that can be applied to optical plastic moldings having a high refractive index, to protect them from deterioration by light without any adverse effect on their optical functions. The coating composition contains the following essential constituents. (A) 1 part of a hydrolyzate of a silane compound; (B) 0.2-5 parts of titanium oxide-based composite fine particles having a particle diameter of 1-100 nm in which titanium oxide integrally combines with (i) iron oxide, with the ratio of iron oxide to titanium oxide being 0.005-0.15 by weight; or (ii) silicon oxide with the ratio of silicon oxide to titanium oxide being 0.03-0.7 by weight; (C) 0.02-0.5 part of an unsaturated or saturated polycarboxylic acid or an anhydride thereof; and (D) 0.01-0.2 part of a heat-curing catalyst. o</p> |
