  • Patent number: 6197282
    Abstract: The present invention provides a method for producing a material dispersed with ultraviolet shielding fine particles, characterized by subjecting a starting material liquid mixture comprising particles comprising one or more inorganic substances having shielding abilities against ultraviolet light, one or more silicone dispersants selected from modified silicones and reactive silicones, and a silicone oil to a mill treatment and/or a high-pressure dispersion treatment; and ultraviolet shielding fine particles or a material dispersed therewith, characterized by being produced by the above method. Also, the present invention provides a method of producing a powdery product of ultraviolet shielding fine particles, characterized by drying the material dispersed with ultraviolet shielding fine particles obtainable by the above method.

  • Patent number: 5827507
    Abstract: The present invention is directed to ultraviolet shielding composite fine particles having transparency in a visible light region, comprising (a) matrix particles comprising an aggregate of primary particles having an average particles diameter of from 0.001 to 0.3 .mu.m, said aggregate being formed while retaining the shapes of the primary particles; and (b) daughter particles having an average particle diameter of from 0.001 to 0.1 .mu.m, said daughter particles being dispersed in and supported by said matrix particles, wherein said daughter particles have a smaller band gap energy than that of particles constituting said matrix particles, and possess capability of absorbing ultraviolet light. The composite fine particles are produced by preparing a liquid mixture containing a mixture comprising starting materials for matrix particles and for daughter particles; forming droplets from the liquid mixture; and drying the formed droplets and/or pyrolyzing starting materials for pyrolysis therein.
