This invention relates to the use of a water-soluble or water-dispersible copolymer comprising, in the form of polymerized units: n (a) at least one monomer compound of general formula I: n n n (b) at least one hydrophilic monomer bearing a function of acidic nature which is copolymerizable with (a) and capable of ionizing in the application medium, n (c) optionally, at least one hydrophilic monomer compound containing ethylenic unsaturation and of neutral charge, bearing one or more hydrophilic groups, which is copolymerizable with (a) and (b), n the a/b molar ratio being between 60/40 and 5/95, n to give a hard surface hydrophilic properties. |
