Abstract
Colored lustrous pigments of superior quality are prepared by dry blending a platy substrate such as a metal oxide-coated mica nacreous pigment and a hydrophobic colorant at low shear. The resulting blend exhibits a well dispersed, stable coloration, increased hydrophobicity and is particularly useful in industrial and automotive applications. The technique can also be employed to prepare pigments for cosmetic application.
