Method for Producing a Multilayer Element, and Multilayer Element

摘要

The invention relates to a method for producing a multilayer body (100, 200, 300, 400), as well as a multilayer body (100, 200, 300, 400) produced thereby. A single- or multi-layered first decorative ply (3) is applied to a carrier ply with a first (11) and a second (12) side. A metal layer (5) is applied to the side of the first decorative ply (3) facing away from the carrier ply and structured such that the metal layer (5) is provided with a first layer thickness in one or more first zones (8) and is provided with a second layer thickness different from the first layer thickness in one or more second zones (9), wherein in particular the second layer thickness is equal to zero. A single- or multi-layered second decorative ply (7) is applied to the side of the metal layer (5) facing away from the first decorative ply (3) and structured using the metal layer (5) as mask such that the first (3) or second (7) decorative ply is at least partially removed in the first (8) or second (9) zones.

1. A method for producing a multilayer body, in particular an optical security element or an optical decorative element, wherein in the method:
a) a single- or multi-layered first decorative ply is applied to a carrier ply; b) at least one metal layer is applied to the side of the first decorative ply facing away from the carrier ply; c) the at least one metal layer is structured such that the metal layer is provided with a first layer thickness in one or more first zones of the multilayer body and is provided with a second layer thickness different from the first layer thickness in one or more second zones of the multilayer body, wherein the second layer thickness is equal to zero; d) a single- or multi-layered second decorative ply is applied to the side of the metal layer facing away from the first decorative ply; e) the first and/or second decorative ply is structured using the metal layer as a mask in a first area of the multilayer body such that the first or second decorative ply is at least partially removed in the first or second zones.
