Finishing agents for textiles, leather, paper and mineral substrates of the type mentioned in the title and the aqueous dispersions prepared therefrom are characterized by the following percentages by weight of the comonomers, relative to the total weight of the copolymers: a) 45-75% by weight of (meth)acrylates containing perfluoroalkyl groups, of the formula CnF2n+1-X-OCO-CR1=CH2(I) b) 10-50% of monomers of the formulae CH2=CH-CO-OR4(IIa) and/or CH2=C(CH3)-CO-OR12(IIb) c) 4-30% of monomers of the formula <IMAGE> (III) d) 1-15% of monomers of the formula CH2CR11COOCH2CH2N(R8, R9)or (IVa) [CH2CR11COOCH2CH2N(R8, R9, R10)(+)Y(-)or (IVb) <IMAGE> (IVc) The monomers in b) can be replaced completely or partially by monomers from the group consisting of styrene, acrylonitrile, vinyl acetate, vinyl propionate and methyl methacrylate. The substituents have the meaning given in the description. |
