    摘要： The aqueous dispersion, characterized in that it comprises 1) at least one vinylidene chloride polymer (Pl) and 2) at least one random, alternating or gradient copolymer (Cl) comprising a) at least one monomer unit (ml) carrying at least one phosphonate group -PO(OH)(OR1) with R1 being a hydrogen atom or an alkyl radical comprising from 1 to 11 carbon atoms, and b) monomer units (ml) which represent at least 50 % by weight of the copolymer (Cl), derived from at least one monomer (M2) chosen from styrene, maleic anhydride, itaconic acid and the (meth)acrylic monomers corresponding to the general formula : CH2 = CR2 R3 in which R2 is chosen from hydrogen and the methyl radical and R3 is chosen from the -CN radical and the -CO-R4 radical in which R4 is chosen from the -OH radical, the -O-R5 radicals with R5 chosen from the linear or branched alkyl radicals comprising from 1 to 18 carbon atoms which optionally carry one or more -OH radicals, the epoxyalkyl radicals comprising from 2 to 10 carbon atoms and the alkoxyalkyl radicals comprising a total of 2 to 10 carbon atoms and finally R4 is also chosen from the -NR6Ry radicals in which R6 and R7, which are identical or different, are chosen from hydrogen and the alkyl radicals comprising from 1 to 10 carbon atoms which optionally carry one or more -OH radicals.
