A primer composition comprises (A) a vinyl copolymer obtained through copolymerization of (a-1) a UV-absorbing vinyl monomer, (a-2) an alkoxysilyl group-containing vinyl monomer, and (a-3) another copolymerizable monomer, (B) a curing agent, and (C) a thermoplastic vinyl resin having a Tg of at least 80°C. Polycarbonate resin articles, when covered with an undercoat of the primer composition and an overcoat of an organopolysiloxane composition, exhibit improved transparency, mar resistance, weather resistance, and chemical resistance and find outdoor use as vehicle and building windows and windshields.
一种底漆组合物包括(A)通过(a-1)紫外线吸收乙烯基单体、(a-2)含烷氧基硅基的乙烯基单体和(a-3)另一种可共聚单体的共聚得到的乙烯基共聚物;(B)固化剂;以及(C)Tg 至少为 80°C 的热塑性乙烯基树脂。聚碳酸酯树脂制品在涂上底漆组合物的底层和有机聚硅氧烷组合物的外层后,透明度、抗磨损性、耐候性和耐化学性均得到改善,可在室外用作汽车和建筑物的窗户和挡风玻璃。
