Abstract
The invention relates to a multilayer foil, in particular a transfer foil. The transfer foil consists of a carrier. foil, a one- or multilayer transfer layer containing an optically variable structure, and an intermediate layer located between the carrier foil and the transfer layer, the intermediate layer being a metal oxide or semiconductor oxide layer.
Claims15
A foil multilayer transfer material including a carrier band, a reaction lacquer layer which is provided with a holographic embossing and at least one plastic layer and an intermediate layer located between the carrier band and the plastic layer, wherein the intermediate layer comprises a metal oxide or semiconductor oxide layer.
A method for producing a multilayer transfer material having a carrier band, a reaction lacquer layer which is provided with a holographic embossing, at least one plastic layer and an intermediate layer located between the carrier band and the plastic layer, comprising applying a metal or semiconductor oxide layer to one surface of the carrier band as an intermediate layer and covering this intermediate layer by application of the plastic layer, and providing a reaction lacquer layer with a holographic embossing.
