Summary: | The present invention relates to the use and application of a water-soluble or water-dispersible copolymer comprising: a) at least a monomer compound of general formula i: in which R1 is a hydrogen atom, a methyl or ethyl group; R2, R3, R4, R5 and R6, which are identical or different, are linear or branched C1-C6, alkyl, hydroxyalkyl or aminoalkyl groups; m is an integer from 0 to 10; n is an integer from 1 to 6; Z represents a -C(O)O- or -C(O)NH- group or an oxygen atom; A represents a (CH2)p group, p being an integer from 1 to 6; B represents a linear or branched C2-C12, polymethylene chain optionally interrupted by one or more heteroatoms or heterogroups, and optionally substituted by one or more hydroxyl or amino groups; X, which are identical or different, represent counterions; and (b) at least one hydrophilic monomer carrying a functional acidic group which is copolymerizable with (a) and which is capable of being ionized in the application medium; (c) optionally at least one monomer compound with ethy |
