Abstract
The present invention relates to a composition coextrudable with PVDF and comprising: 30 to 50 parts of PVDF; 70 to 50 parts of a copolymer comprising, by weight, 90 to 50% of methyl methacrylate (MMA) per 10 to 50% of an alkyl (meth)acrylate respectively, the alkyl having from 2 to 24 carbon atoms; 1 to 4 parts of a UV absorber; the total making 100 parts. The invention also relates to coextruded films consisting of this composition as the adhesive layer and a PVDF-based layer of 50 to 100 parts of PVDF per 50 to 0 parts of PMMA respectively. These films possess mechanical properties sufficient to allow them to be used as a coating transparent to visible light but opaque to UV radiation.
