ABSTRACT:
A titanium oxide-coated chromatic-color metal flake pigment is prepared by hydrolyzing an organic titanate ester compound, e.g., tetraisopropoxy titanium, in the presence of the base metal flakes suspended in an organic medium having a pH of 4 to 8. The pigment exhibits iridescent color tones of great aesthetic value delicately varying depending on the thickness of the titanium oxide coating layer. The pigment has high chemical stability, for example, against acids, by virtue of the very uniform and dense coating layer of titanium oxide so that the inventive pigment is useful as a coloring agent in a water-borne composition.
