摘要： A nanocomposite particle comprises a core particle being one organic molecule or an assembly of organic molecules; and a shell layer enclosing the core particle and comprising organic titanosilicate which comprises an Si and Ti oxide containing a bond expressed by M-O-M, where M is Si or Ti, and has an organic group bonded to at least part of silicon atoms. Because of being enclosed by the shell layer, the organic molecule is shielded from substances causing degradation of the organic molecule. Therefore, when the organic molecule contains an ultraviolet absorbing molecule or a pigment molecule, its ultraviolet absorbing effect or its coloring property is maintained for a long time. Besides, since the shell layer comprises organic titanosilicate, the nanocomposite particle is excellent in dispersibility, for example, in a coating composition including resin vanish.

摘要翻译： 纳米复合颗粒包括核心颗粒是一个有机分子或有机分子的组合; 以及壳层，其包围所述核心颗粒并且包含有机钛硅酸盐，所述有机钛硅酸盐包含含有由M-O-M表示的键的Si和Ti氧化物，其中M是Si或Ti，并且具有与至少部分硅原子键合的有机基团。 由于被壳层包围，有机分子被屏蔽了导致有机分子降解的物质。 因此，当有机分子含有紫外线吸收分子或颜料分子时，其紫外线吸收效果或其着色性能长时间保持。 此外，由于壳层包含有机钛硅酸盐，所以纳米复合粒子的分散性优异，例如在包含树脂消失的涂料组合物中。
