ABSTRACT:
The present invention relates to a pigment and a coating composition comprising such a pigment, wherein it is contemplated that a coating composition containing such pigment is capable of inhibiting corrosion of a substrate to which it is applied. In one embodiment, the pigment comprises a filler having calcium borate, calcium molybdate, and calcium phosphate deposited on the surface of the filler. In an exemplary embodiment, the filler is calcium carbonate.
