The invention relates to the use of a water-soluble or water-dispersible copolymer comprising, in the form of polymerized units: (a) at least one monomeric compound of general formula I: (CF DRAWING IN BOPI) (b) at least one hydrophilic monomer having a function with an acidic character copolymerizable with (a) and capable of ionizing in the application medium (c) optionally at least one hydrophilic monomer containing hydrophilic ethylenically unsaturated ethylenically unsaturated, copolymerizable with (a) and (b), the molar ratio a / b being between 60/40 and 5/95, to impart hydrophilic properties to a hard surface. |
