摘要:
The present invention provides a glass flake having sufficiently high visible-light absorptivity. The glass flake of the present invention includes a glass composition that contains a transition metal oxide such as an iron oxide and that allows the glass flake to have a visible-light transmittance of 85% or lower measured with an A light source when the glass flake has a thickness of 15 μm. In this glass composition, it is preferable that the content of Fe2O3 (T−Fe2O3) in terms of the total iron satisfies the following formula, expressed in mass %: 10

摘要:
The present invention provides a flaky black bright pigment which exhibits a black color having brightness and a high hiding power, and thus a cosmetic or the like containing the pigment is excellent in the touch feeling, smoothness and spread during use. The pigment is a black bright pigment which comprises a flaky base material having an average thickness of 0.1 to 8.0 μm, an average particle diameter of 1 to 800 μm, and an aspect ratio of 3 to 500, wherein the surface of the base material is coated with a thin film of triiron tetroxide and/or a low order titanium oxide. The thickness of the thin film is preferably 10 nm to 1.0 μm, and the pigment has preferably a brightness (L15 value) of 40 or higher.
