Abstract

The invention relates to a process for producing a multilayer body (12), to a multilayer body (12), to the use of a multilayer body (12), to the use of a first layer (1) of a first metal and a second layer (2) of a second metal in a multilayer body (12) and to the use of a heat application apparatus (14). The multilayer body (12) comprises a first layer (1) of a first metal and a second layer (2) of a second metal, wherein the first (1) and the second layer (2) are arranged directly atop one another in at least one first region (10), so that in the at least one first region (10) the visual appearance and/or the physical properties of the first (1) and/or second layer (2) are altered, in particular on account of a chemical and/or physical reaction of the first (1) and the second layer (2) with one another.
