The present invention lies in the field of nitrocellulose nail varnishes and its subject is the use of an arylsulphonylurethane as film forming resin in these varnishes, which makes it possible in particular to avoid the release of formaldehyde, a carcinogenic compound which is formed when an arylsulphonamide-formaldehyde resin is employed. Another subject of the invention is new poly(arylsulphonylurethanes) containing from 2 to 5 arylsulphonylurethane groups and possessing a molecular mass of between 450 and 1500.
