Curable fluoro copolymer containing the residues from copolymerisation of a fluoro monomer and of an allyl monomer, characterised in that …… a) the residues of fluoro monomer originating from the combined use of tetrafluoroethylene and of at least one other fluoro monomer chosen from chlorotrifluoroethylene and vinylidene fluoride … b) the allyl monomer is an allyl polyol of formula ……… … R1 being H or CH2OH … R2 being OH or CH2OH … R3 being CH3 or OH …it being known that R1 and R3 cannot simultaneously be H and CH3 … and in that it contains: … c) the residues of an allyl or acrylic monomer bearing a fluorocarbon chain of formula …… with …… n being a value from 3 to 12 … R4 being H or CH3 … X being ……… ……This curable copolymer is obtained by copolymerisation in solution in an organic solvent. In solution in a suitable solvent, this copolymer is employed in paints or varnishes which resist stains and dirt.
