In the present invention, the formula K z / n [Li x Mg (3.0- (x + y) □ y Si 4 O 10 F 2 ] (I) (In the equation, n is the charge of K, z = x + 2y, where 0.2 <z <0.8, x = 0-0.8, y = 0-0.4. And K is selected from the first group consisting of Li + , Na + , K + , NH 4 + , Rb + , Cs + , Mg 2+ , Ca 2+ , Sr 2+ , Ba 2+ or a mixture thereof. Cations, cations selected from a second group consisting of alkylammonium salts having 2 to 8 C atoms (where alkyl can be branched or linear), or first and second groups. A cation selected from a mixture of cations from the group of We handle effect pigments including Hectrite. Further, these colored hectorites may include a coating on which at least one layer having a high index of refraction greater than 1.8 or a translucent metal and optionally an outer protective layer is included. |
