(Iii) a first layer of colorless transparent high refractive index metal oxide,n n n (Ii) a second layer of colorless transparent low refractive index metal oxide, andn n n (Iii) a multilayer interference pigment composed of a cobalt aluminate, a coating formed from a third outer layer of cobalt-containing glass or cobalt oxide, and a platelet-shaped carrier material, having a blue mass tone. It is also possible for the first and third layers to be interchanged.n n n The high refractive index metal oxides used are titanium dioxide, zirconium dioxide or tin oxide. The low refractive index metal oxides used are silicon dioxide or aluminum oxide. |
