    摘要: Nail polish is disclosed, based upon a film-former, a resin component and a solvent system, containing as film-former and/or resin component an O-benzyl-N-hydroxyalkyl chitosan fo the formula (I)HO[C.sub.6 H.sub.11-m-q NO.sub.4 (R.sup.1).sub.m (R.sup.2).sub.n (R.sup.3).sub.q ].sub.p H (I)(with m=0 to 0.6; n=0.1 to 10; q=0.1 to 4; p=an integer from 50 to 5,000; R.sup.1 =acetyl; R.sup.2 =hydroxyethyl, 2-hydroxypropyl or 2-hydroxybutyl and R.sup.3 =benzyl).The polish film obtained with the nail polish possesses a high luster, outstanding adhesion, as well as an increased hardness compared to nail polishes based upon nitro-cellulose, with even more sufficient elasticity. Also included in the present invention are the new O-benzyl-N-hydroxyalkyl-chitosans of formula (I).
