Patent ID: 7658793

Claim:
A composite pigment based on at least one inorganic pigment and at least one organic pigment, wherein the pigment contains composite particles in which organic pigment particles adhere to inorganic pigment particles, and wherein the organic pigment particles are more finely divided than the inorganic pigment particles, and further wherein the composite particles have an organic macromolecular coat, wherein the organic macromolecular coat is a surface-active organic macromolecular coat and wherein the particles of the inorganic and organic pigments are wet ground in the presence of the organic macromolecular coat, and the inorganic pigment particles comprising at least one of nickel-antimony-titanium oxide and chromium-antimony-titanium oxide; and, a surface of the composite particles which contain the inorganic and organic pigment particles, are provided with an additional siloxane and/or silane coat to reduce attrition by abrasion and to improve dispersibility.
