A clear coating composition for use over nail polish. The clear coating composition comprises (a) a crosslinkable coating composition comprising: ingredient A that has at least two protons that can be activated to form a Michael carbanion donor ingredient B that functions as a Michael acceptor having at least two ethylenically unsaturated functionalities each activated by an electron-withdrawing group and a dormant carbamate initiator of Formula (1)wherein R1 and R2 can be independently selected from hydrogen, a linear or branched substituted or unsubstituted alkyl group having 1 to 22 carbon atoms 1 to 8 carbon atoms 1 to 3 carbon atoms and An+ is a cationic species or polymer and n is an integer equal or greater than 1 with the proviso that An+ is not an acidic hydrogen an ingredient D having one or more reactive protons that are more acidic than the two protons of ingredient A, with respect to pKa at least one organic solvent with the proviso that the clear coating composition is free of FD&C or D&C dyes, lakes or pigments. The clear coating composition optionally further comprising ammonium carbamate (H2NR1R2+−OC═ONR1R2).
