Abstract
Description
technical field
[0001] The invention relates to effect pigments based on glass flakes coated with metallic silver and to a process for producing the pigments. The pigment has strong silvery-white reflective brightness and shimmering effect, and can be used as an effect pigment in any pigment field, and is widely used in cosmetics, decorative materials, inks, paints, etc. Background technique
[0002] As a typical representative of effect pigments, pearlescent pigments are formed by coating metal oxides on flake substrates. At present, the most widely used metal oxides are titanium dioxide and iron oxide. Due to the refraction and reflection of light, the absorption of light and the interference of light, pearlescent pigments can exhibit pearlescent luster ranging from silvery white to various colors. Due to the unsatisfactory transparency of mica itself, the brightness and flash effect of this kind of pigments are poor. For many years, researchers have been trying to find ...
