Abstract

Laminated air-gap interference pigments are characterized by contiguous layers of medium- to low-refraction minerals with thin intercalated air-gaps less than 1 mu m thick, and by a diameter-to-thickness ratio of the laminae between 1:5 and 1:50. The pigments are obtained by subjecting three- and four-layer phyllosilicates to a heat treatment at a temperature greater than that at which H20, OH or F are released.
