To provide a UV ray-shielding inorganic soft aggregate powder that can be uniformly dispersed in a polymer matrix comprising an organic polymer, to provide a UV ray-shielding inorganic particle-organic polymer composite paste comprising the above UV ray-shielding inorganic soft aggregate powder and the organic polymer, and to provide a UV ray-shielding inorganic particle-organic polymer composite material having little deterioration after irradiation with UV rays.
The UV ray-shielding soft aggregate powder is obtained by preparing slurry containing UV ray-shielding inorganic particles, which are obtained by disintegrating a UV ray-shielding inorganic source powder through a mill process without damaging the particle surfaces, and freeze-drying the slurry. The UV ray-shielding inorganic particle-organic polymer composite paste includes the obtained UV ray-shielding inorganic soft aggregate powder and the organic polymer, and the UV ray-shielding inorganic particle-organic polymer composite material obtained from the UV ray-shielding inorganic particle-organic polymer composite paste suppresses deterioration after irradiation with UV rays.
