| description | A pearlescent pigment, wherein the pigment is an inorganic material and the color of a homogeneous coating of the pigment, measured over a black background has a CIELAB hue angle, hab, from about 40 to about 320 degrees, wherein L* is from about 35 to about 80, and the chroma value is less than 5. A substrate is coated with iron oxide by oxidizing an iron salt to form a pigment. The pigment may be made by a process of coating iron oxide on a substrate by oxidizing an iron salt. During the coating of the iron oxide, the pH of the mixture is increased. The coating formed has a Fe(III)/Fe(Il) ratio of greater than 2. The pigments may be used in a variety of applications including coating, ink, plastic, and cosmetic compositions.
L'invention concerne un pigment perlé, le pigment étant un matériau inorganique. La couleur d'un revêtement homogène du pigment, mesurée sur un fond noir, possède un angle de teinte CIELAB, hab, d'environ 40 à environ 320 degrés. Le L* varie d'environ 35 à environ 80, et la valeur chromatique est inférieure à 5. Un substrat est recouvert d'oxyde de fer en oxydant un sel de fer pour former un pigment. Le pigment peut être fabriqué par un procédé qui consiste à revêtir un substrat d'oxyde de fer en oxydant un sel de fer. Pendant le revêtement de l'oxyde de fer, le pH du mélange est augmenté. Le revêtement formé a un rapport Fe(III)/Fe(II) supérieur à 2. Les pigments peuvent être utilisés dans une variété d'applications, y compris des compositions de revêtement, d'encre, de plastique et cosmétiques. |
