MULTILAYER INTERFERENCE PIGMENT WITH TRANSPARENT CENTRAL LAYER

摘要

The invention concerns a multilayer interference pigment consisting of a central layer of a transparent or semi-transparent material with a low refraction coefficient and alternating layers of a metal or a material with a high refraction coefficient and a material with a low refraction coefficient on both sides of the central layer. The material with a low refraction coefficient is preferably magnesium fluoride or acrylate and the metal is preferably aluminium or chromium.
