Abstract:
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 νm and retaining their shapes as such and daughter particles having a mean diameter of 0.001 to 0.1 νm 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.
Abstract:
