摘要：A aqueous, radiation curable, coating composition is disclosed which comprises:(A) from 50 to 85 percent, based on the total weight of the dispersion, of a vinylfunctional silane, (B) from 15 to 50 percent, based on the total weight of the dispersionof a multifunctional acrylate, and (C) optionally, from 1 to 3 weight percent of aphotoinitiator. The vinyl-functional silane is the partial condensate of silica and a silane,such that at least sixty percent of the silane is a vinyl-functional silane conforming to theformula
(R).sub.a Si(R').sub.b (R\").sub.c
wherein
R is allyl or vinyl functional alkyl
R' is hydrolyzable alkoxy or methoxy< P>
R\" is non-hydrolyzable, saturated alkyl, phenyl, or siloxy,
such that a+b+c=4; and
a≧1;< P>
b≧1;
c≧0.
The above described coating composition may be applied to plastic materials andcured by exposure to ultraviolet or electron beam irradiation to form a substantiallyclear, abrasion resistant layer. The radiation curable composition has particular utility asan abrasion resistant coating for synthetic films, preferably polyester films. Such coatedfilms may then be employed in automotive glazing and touch panel control applications.
