摘要： The ultraviolet shielding composite fine particles having transparency in a visible light region include (a) matrix particles comprising an aggregate of primary particles having an average particle diameter of from 0.001 to 0.3 mu m, the aggregate being formed while the primary particles retain their shapes; and (b) daugther particles having an average particle diameter of from 0.001 to 0.1 mu m, the daughter particles being dispersed in and supported by the matrix particles. In the composite fine particles, the daugther particles have a smaller band gap energy than the particles constituting the matrix particles and are capable of absorbing ultraviolet light, and the resulting ultraviolet shielding composite fine particles have substantially no catalytic activities.

摘要： An ultraviolet-screening composite particulate transparent in the visible region, characterized in that it is constituted of a matrix particle formed by the agglomeration of primary particles having sizes of 0.001 to 0.3 mu m and retaining their shapes as such and daughter particles having a mean diameter of 0.001 to 0.1 mu m and dispersed and immobilized in the matrix particle, the daughter particles having a smaller band gap energy than that of the primary particles constituting the matrix particle and exhibiting an ultraviolet-absorbing power, that it has a structure wherein the surface is coated with at least one silicone selected from the group consisting of modified silicones, reactive silicones and silicone-modified copolymers, and that it is substantially free from catalytic activity. Thus, the composite particulate contains ultrafine particles having an ultraviolet-screening power and is surface-coated with a silicone, so that it is substantially free from catalytic activity and can efficiently screen ultraviolet rays while having a high transparency in the visible region.
