    摘要: A curable composition comprises (A) a vinyl polymer having hydrolyzable silyl groups and/or SiOH groups and organic UV absorbing groups bonded to side chains, (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, and (C) an organosilicon compound containing a nitrogen atom and an alkoxysilyl group in the molecule. The curable composition is coated and cured to an article, whereby the article is endowed with satisfactory weathering resistance while minimizing coloration or degradation.
