摘要:
A multilayered article is disclosed, which includes, in sequence: (1) a substrate (S), e.g., of thermoplastic polycarbonate; (2) a scratch-resistant layer (SR); and (3) a top layer (T). The scratch-resistant layer is prepared by curing a scratch-resistant coating composition comprising a polycondensate prepared from at least one silane, said polycondensate being prepared by a sol-gel process. The top layer is prepared by curing a top layer coating composition prepared by hydrolyzing a composition which includes: at lest one compound represented by general formula I, M(R′)m (I) wherein M is an element selected from the group consisting of Si, Ti, Zr, Sn, Ce, Al, B, VO, In and Zn, R′ represents a hydrolysable radical, and m is an integer from 2 to 4; and optionally at least one compound represented by general formula II, RbSiR′a, (II) wherein the radicals R′ and R are the same or different, R′ is as defined for general formula (I), R represents a group selected from an alkyl group, an alkenyl group, an aryl group, a hydrocarbon group with at least one halogen group, an epoxide group, a glycidyloxy group, an amino group, a mercapto group, a methacryloxy group and a cyano group, and a and b independently of one another have a value from 1 to 3, provided that the sum of a and b is four. The multilayered articles are distinguished by possessing outstanding scratch and abrasion resistance.
