Abstract
The invention relates to an article containing at least three layers, which is intended to adhere to a polymer incompatible with polyvinylidine fluoride (PVDF). The article comprises at least one layer of PVDF, at least one layer of PVDF rendered opaque to UV and visible radiation, and a composition for adhesion of the PVDF to an incompatible thermoplastic. The three-layer complex may be obtained by coextrusion. The three-layer complex is generally intended to form, with a PVDF-incompatible thermoplastic material, a novel 4-layer integral complex, either by coextrusion or by hot-pressing.
