The invention concerns a the use of a water soluble or water dispersible copolymer comprising, in the form of polymerised units: (a) at least a monomer compound of general formula (I); (b) at least a hydrophilic monomer bearing a function with acid character copolymerisable with (a) and capable of being ionised in the medium where it is to be used; (c) optionally an ethylenically unsaturated hydrophilic monomer compound of neutral charge bearing one or several hydrophilic groups, copolymerisable with (a) and (b), the a/b molar ratio ranging between 60/40 and 5/95, to provide a hard surface with hydrophilic treatment.
Cette invention concerne l'utilisation d'un copolymère hydrosoluble ou hydrodispersable comprenant, sous la forme d'unités polymérisées:(a) au moins un composé monomère de formule générale (I): (b) au moins un monomère hydrophile portant une fonction à caractère acide copolymérisable avec (a) et susceptible de s'ioniser dans le milieu d'application:(c) éventuellement au moins un composé monomère hydrophile à insaturation éthylénique de charge neutre portant un ou plusieurs groupes hydrophiles, copolymérisable avec (a) et (b), le rapport molaire a/b étant compris entre 60/40 et 5/95, pour conférer à une surface dure des propriétés d'hydrophilisation.
