Description
An organic pigment prepared by precipitation of a dye on a powdered, inorganic substrate. Because of its transparency, Alumina trihydrate, is the most commonly used substrate or carrier. Baryte (Barium sulfate), produces an opaque lake pigment. Other compounds used as carriers are: Chalk, Clay, Gypsum, Zinc oxide, White earth, and Green earth. Often a mordant, such as Tannic acid, Lactic acid, or sodium phosphate, is used to fix the dye to the substrate. Many natural dyes were made into lake pigments, such as Cochineal, Kermes, Madder, and lac for use in oil painting. Some modern synthetic dyes, such as aniline dyes, are also prepared in this manner for use as paint pigments. Lake pigments are used in painting, printing inks, plastic colorants, and coated fabrics.
