Coated shaped articles and method of making same.

摘要

Disclosed are shaped articles having a coating layer formed on surface region, wherein the surface region is formed of a polymer derived from a multifunctional acrylic monomer containing two or more (meth)acryloyloxy groups and having 0.02 to 0.2 mu mol/cm<2> of acidic groups therein, by curing a coating composition consisting essentially of a specific silica polycondensate. The silica polycondensate is obtained by mixing (I) colloidal silica and (II) a specific silicon compound in such a molar ratio that the average number of hydrolyzable groups is within the range of 2.30 to 3.85, and then subjecting them to cohydrolysis and polycondensation. In these shaped articles, the coating layer have excellent properties such as hardness and abrasion resistance, as well as good adhesion.
