Title: USE OF AN AMPHOTERIC POLYMER FOR TREATING A HARD SURFACE
Abstract:
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.
