(57) Abstract :
The invention concerns a multilayer structure comprising: a PVDF-based film Flaffixed to a PET or PEN sheet or a PVDF-based film
Fl affixed to a PET or PEN sheet which is itself affixed to a PVDF-based film F2, The Fl and/or F2 films comprising (starting from
the PET or PEN sheet): optionally a layer of composition B including 5 to 40 parts of at least one PVDF, 60 to 95 parts of at least one
PMMA and 0 to 5 parts of at least one UV absorber, the total being 100 parts; a layer of composition A, including 50 to 100 parts of at
least one PVDF, 0 to 50 parts of at least one PMMA, 0 to 30 parts of at least one mineral filler and 0 to 3 parts of at least one
dispersant, the total being 100 parts; optionally a layer of composition C including 80 to 100 parts of at least one PVDF, 0 to 20 parts
of at least one PMMA, 0 to 30 parts of at least one mineral filler and 0 to 3 parts of at least one dispersant, the total being 100 parts;
such that and adhesive layer is interposed between the PET or PEN sheet and the Fl and/or F2 films, said adhesive layer being optional
if the layer of composition B is present and not including any polyolefin functionalized by an unsaturated acid or anhydride or a ho
mo-or copolymer including as monomers) acrylic acid, acrylates and alkyl acrylates optionally modified by an unsaturated acid or
