Verfahren zur Herstellung von verschleißfesten farbigen Schichten und deren Verwendung

The invention relates to a process for producing coloured layers in the vacuum by the simultaneous vapour deposition of dielectrica and at least one dye which can be organically vapour-deposited or sublimated from separate vapour depositing sources onto a substrate, whereby at least two subcoatings, one dye-rich coating and one low-dye coating is applied on top of each other by changing the depositing rate of a vapour source.
