Abstract:
The present invention relates to pearlescent pigments, to a process of manufacturing such pearlescent pigments based on a wet oxidation step as well as to the use of such pearlescent pigments.

Claim (Index 1):
A process of manufacturing pearlescent pigments, comprising the steps of:\n providing substrates of monolithically structured aluminum platelets having an average thickness of from 1 to 150 nm, and having an aspect ratio expressed by the ratio of the average size to the average thickness of at least 80; coating the above aluminum platelets with a coating layer A of silicon dioxide; coating the such coated aluminum platelets with a coating layer B of a metal oxide as an interference layer, with the metal oxide being other than silicon dioxide and having a refractive index of at least 1.8; wet-oxidizing under basic conditions the above aluminum platelets, either before or after coating with the coating layers A and B, whereby the aluminum platelets are partially or entirely converted into aluminum oxide or aluminum hydroxide; and subsequently isolating the partially or entirely wet-oxidized aluminum platelets coated with the coating layers A and B.
