  • Patent number: 6740315
    Abstract: Coated powder is obtained by applying a material having a refractive index of 1.9 to 3.1 to powder having a refractive index of 1.3 to 1.8 as a core and further applying a material having a refractive index of 1.3 to 1.8 to the coated core. When this powder is used for cosmetics or paints, natural coloring can be accomplished without deteriorating lightness because a screening effect is not high.
