  • Patent number: 5690916
    Abstract: In order to make a hyperchromic portion of the skin, which has been caused by nevus, angioma, red face, spots, freckles, and the like, inconspicuous, a material having as a transmitted light component, a color gamut which is a complementary color for the skin color to be adjusted or in proximity to that complementary color is compounded in a skin-color adjusting composition. When this composition is applied on the hyperchromic portion of the skin, the hyperchromic portion naturally becomes inconspicuous without deteriorating the transparent feel of the skin.Also, in the colored titanium oxide coated mica is characterized that, as a skin-color adjusting composition, a fine particle of iron oxide having an average particle diameter of 60-150 nm is coated on the titanium oxide coated mica, so as not to be big the absorption of light by iron oxide on the surface and not to be weakened by the transmitted interference color.

  • Patent number: 5567754
    Abstract: Thermoplastic concentrates comprising inorganic pigments, such as titanium dioxide, treated with a partial ester polyol and unsaturated monocarboxylic acid treating agent, of the formula R(OH).sub.x COOR', wherein R is an alkyl or aryl radical containing from about 2 to about 20 carbon atoms, R' is an unsaturated alkyl radical containing from about 6 to about 20 carbon atoms, and x is a number from about 2 to about 6, are disclosed. Such treatment improves the dispersibility of the pigments in thermoplastic resins. The treatment also enables the production of thermoplastic concentrates comprising a high percentage of treated inorganic pigment dispersed in a thermoplastic resin.

  • Patent number: 5114486
    Abstract: A new process for the production of pigments suitable for use in paper laminates has been developed in which a metal oxide is treated with a water-soluble salt of zinc and a phosphate or phosphoric acid and subsequently with an alkali metal aluminate in such a manner that there is deposited on the metal oxide a coating containing zinc and phosphate ions together with aluminium ions. The pH of the dispersion following the metal oxide is maintained at a value not exceeding 8.0 during precipitation. A particularly useful pigment is produced which has a coating containing zinc ions in an amount of 0.5 to 5% by weight as ZnO, phosphate ions in an amount of 0.2 to 3% as P.sub.2 O.sub.5 and aluminium ions in an amount of 0.5 to 5% expressed as Al.sub.2 O.sub.3 on the weight of TiO.sub.2.
