Abstract: A modified organic pigment can be used to make a coating composition, such as a paint, a varnish, or a printing ink. The modified organic pigment is obtained by reacting the pigments during the pigment synthesis with one interface-active compound, where the interface-active compound is a compound within a three-dimensional Hansen space determined by three coordinates, Hansen solubility parameters (HSPs), D=18.21, P=8.44, H=13.16 with a radius of 6.7 units about a center of the three-dimensional Hansen space, determined with the aid of the HSPiP software, version 5.0.0.4.

Abstract: A composition can exhibit improved ion resistance and color stability. The composition includes a pigment made of bismuth vanadate (BiVO4). The pigment is in the form of particles coated with at least one O-functionalized carbohydrate, where the O-functionalized carbohydrate is at least one of an ether of a carbohydrate and an ester of a carbohydrate. The carbohydrate is at least one of a monosaccharide and an oligosaccharide. The oligosaccharide is at least one of an oligosaccharide having two to ten monosaccharides, a sugar alcohol, a sugar acid, and a lactone of the sugar acid.
