  • Patent number: 8153163
    Abstract: The present invention relates to a pearl pigment obtained by coating the surface of a flaky powder with a colored metal or a colored metal oxide and further coating the surface of the above colored metal- or colored metal oxide-coated flaky powder with a colorless metal or a colorless metal oxide, wherein when the pearl pigment is applied onto the surface of black artificial leather in an average amount of 0.05 mg/cm2 and the intensity of light reflected from the pearl pigment is measured using illuminant C at a 2° viewing angle with a spectrophotometric colorimeter which is provided with a sheet polarizer S on the light incident side and a sheet polarizer P on the light receiving side, the powder reflection light which is incident to the pearl pigment as a measurement sample at an angle of 45° to the direction normal to the surface of the sample and is received in the direction normal to the surface of the sample has absolute values a* and b* of 10 or less, and make-up cosmetics containing the pearl pigment.
