Abstract
A pearlescent effect pigment having an opaque, dark or black color is disclosed. The black pearlescent pigment includes a platelet-shaped non-metal substrate, optionally an oxide layer, a template layer, and a metal layer. The pearlescent luster of the disclosed effect pigment is comparable to those of pure pearlescent effects. The disclosed method provides a cost-effective approach for the manufacturing of the disclosed effect pigment.
