摘要: A curable composition comprises (A) an organic/inorganic composite in which a hydrolyzable silyl group and/or SiOH group-containing polysiloxane is bonded to a vinyl polymer through a Si-C bond, and (B) an organic UV absorber having a molecular weight of at least 500 and a weight retentivity of at least 95% when held at 150°C for 24 hours in an open state. The curable composition is coated and cured to an article, whereby the article is endowed with satisfactory weathering resistance while minimizing coloration or degradation.
