Patent ID: 8016934

Claim:
A pearl pigment, comprising: flaky powder particles, wherein the surface of said particles are directly coated with a colored iron (III) oxide to form a first coating, wherein said colored iron (III) oxide-coated flaky powder particle is further coated with a second coating of a colorless metal or a colorless metal oxide, wherein said second coating is directly adjacent to said first coating, wherein the thickness of said first coating is less than the thickness of said second coating and said second coating has a geometric thickness ranging from 80 to 360 nm, and wherein when said pearl pigment is applied onto the surface of black artificial leather in an average amount of 0.05 mg/cm 2 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, wherein the colorless metal is titanium or the colorless metal oxide is titanium oxide.
