摘要
This invention deals with effect pigment comprising a colored hectorite which is produced by ion exchange process of an initial hectorite with a cationic dye, wherein the initial hectorite can be represented by the formula (I) wherein n is the charge of K and z = x+2y with 0.2 z 0.8; x = 0 - 0.8; y = 0 - 0.4; K is a cation chosen from a first group consisting of Li+, Na+, K+, ΝΗ4 +, Rb+, Cs+, Mg2+, Ca2+, Sr2+, Ba2+ or mixtures thereof or from a second group consisting of alkylammonium salts with 2 to 8 C-atoms, wherein the alkyl can be branched or linear, or from a mixture of cations from the first and the second group and □ represents not occupied octahedral lattice sites. Furthermore, these colored hectorites can have a coating thereon comprising at least one layer with a high index of refraction 1.8 or a semitransparent metal and optionally an outer protective layer.
