Abstract:
The invention relates to extended, organic pigments, their method of manufacture and their use in paint formulations, particularly those suitable for road or traffic markings. The subject pigments typically comprise a particulate lithopone core coated with a layer of an organic pigment. According to preferred embodiments, the pigment comprises an azo compound, the pigments are rosinated, and/or the core also contains a colorant or doping material, typically a metal oxide or metal salt. An exemplary method involves mixing particulate lithopone with a coupler such as acetoacet-o-anisidide. A coupler precipitator, typically an acidifier, is then added in an amount sufficient to precipitate the coupler onto the lithopone. The lithopone-bound coupler is then reacted with a diazonium ion in an azo-coupling reaction to form a pigment. The pigment-coated lithopone particles may then be heated and coated with a rosin or modified rosin soap.
