THERMOCHROMIC POLYMER LAYER AND METHOD FOR PRODUCING SAID LAYER

摘要

The invention relates to a thermochromic polymer layer, in addition to a method for producing said layer. Said method is based on the admixture of a thermochromic dye and optionally further additives at the start of the extrusion process and subsequent extrusion to form a thermochromic polymer layer. The invention also relates to a multi-layer composite system consisting of at least one thermochromic polymer layer and at least one additional layer.
