ABSTRACT:
The invention relates to a thermochromic polymer layer and also a method for production thereof. The method is based on addition of a thermochromic colorant and if necessary further additives at the beginning of the extrusion process and subsequent extrusion to form the thermochromic polymer layer. Furthermore, the invention relates to a multilayer composite system comprising at least one thermochromic polymer layer and also at least one further layer.
