Sinter-gestützte Abscheidung von gleichmässigen nanokristallinen Titandioxid-Beschichtungen auf Al-Flakes in wässriger Lösung

摘要

A process of forming a multi-layered pigment comprising the steps of: providing a metal core material; treating the metal core material with an acid, depositing a passivation layer onto the metal core material; densifying the metal core material having the passivation layer reducing a pore size of the passivation layer; and depositing a high refractive index material onto the sintered material wherein the high refractive index layer is uniform and crack free.
