含氧化钛的涂料组合物和涂覆的制品
摘要：
提供了涂料组合物，其包含(A)1-50重量份包含核/壳型微粒的经表面处理的氧化钛，所述微粒各自由氧化钛核和氧化硅壳组成，并用具有式(I)和式(II)的两种表面处理组分处理，式(I)：R1Si(OR2)3和式(II)：(R3R42Si)2NH，(B)100重量份由(b-1)含有烷氧基甲硅烷基的乙烯基单体、(b-2)UV吸收性乙烯基单体、和(b-3)另外的单体的共聚获得的乙烯基共聚物，和(C)溶剂。该组合物的固化膜具有改善的耐刮性和UV遮蔽性，同时保持可见光透光性。
摘要（英）：

A coating composition is provided comprising (A) 1-50 parts by weight of surface-treated titanium oxide comprising core/shell type microparticles each consisting of a titanium oxide core and a silicon oxide shell, which are treated with two surface treating components having formula (I): R 1 Si(OR 2 ) 3 and formula (II): (R 3 R 4 2 Si) 2 NH, (B) 100 parts by weight of a vinyl copolymer obtained from copolymerization of (b-1) an alkoxysilyl-containing vinyl monomer, (b-2) a UV-absorbing vinyl monomer, and (b-3) another monomer, and (C) a solvent. A cured film of the composition has improved mar resistance and UV shielding while maintaining visible light transparency.
