| abstract |
A crosslinkable coating composition comprising: Ingredient A having at least two protons that can be activated to form a Michael carbanion donor; Ingredient B, functioning as a Michael acceptor and having at least two olefinic unsaturated functional groups, each activated by an electron withdrawing group; and a dormant carbamate initiator of general formula (1), wherein R 1 and R 2 can be independently selected from hydrogen, linear or branched substituted or unsubstituted alkyl groups having 1 to 22 carbon atoms, 1 to 8 carbon atoms; and A n+ is a cationic active species or polymer, and n is an integer equal to or greater than 1, provided that A n+ is not an acidic hydrogen; and optionally further comprises ammonium carbamate (H 2 NR 1 R 2 + -OC=ONR 1 R 2 ). The crosslinkable coating compositions can be used in various coating applications including nail coating compositions. |
