CA 2086276

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 acryl- is monomer and having 0.02 to 0.2 µmol/cm2 of acidic groups therein, by curing a coating composition consist- ing essentially of a specific silica polycondensate. The silica polycondensate is obtained by mixing (T) 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.
