Abstract:
An article with a continuous structure, comprising at least three layers, whereinan outermost layer consisting essentially of PVDF; a middle layer consisting of PVDF homopolymer and/or PVDF copolymer containing at least 70% by weight of residue of vinylidene fluoride molecules and at least one agent selected from the group consisting of fillers, pigments, UV-absorbing agents, UV-stabilizing agents and plasticizers; and an inner layer comprises a composition which allows adhesion of PVDF to a PVDF-incompatible thermoplastic polymer wherein the outermost layer has a light transmission such that the absorption of photons of wavelength 800 nm on a 50 &mgr;m film is less than 70% and the middle layer has a light transmission such that the absorption of photons of wavelengths between 200 and 800 nm on a 50 &mgr;m film is greater than 90%.
