Abstract:
A nail enamel composition which provides a semi-permanent, crosslinked film on the nail after application thereto, comprising:(a) 1-80% by weight of the total composition of a film-forming polymer having functional groups capable of cross-linking upon exposure to a cross-linking agent reactive with said functional groups,(b) 0.1-70% by weight of the total composition of a cross-linking agent reactive with said functional groups of the film-forming polymer selected from the group consisting of(i) metal ions having a coordination number greater than or equal to 2,(ii) multifunctional alcohols,(iii) polymeric polyols,(iv) primary, secondary, or tertiary amines having the formulas RNH.sub.2, RR'NH.sub.2, RR'R""NH.sub.2 wherein R, R' and R"" are each independently a multivalent aliphatic, aromatic, or heterocyclic moiety,(v) polyalcohols,(vi) aliphatic or aromatic aldehydes,(vii) thermosetting resins; and(viii) salts of multi-valent ions(c) 0.001-40% by weight of the total composition of a dissipatable blocking agent which (i) is operable prior to dissipation, to block the cross-linking agent from cross-linking the functional groups of the film-forming polymer, and which, (ii) after dissipation, leaves the cross-linking agent free to cross-link the functional groups of the film-forming polymer.
