Patent ID: 7998653

Claim:
A coating composition comprising a latent activator, wherein the latent activator is a salt of an acid and an amine, wherein the amine is of formula NR 1 R 2 R 3 , wherein R 1 , R 2 and R 3 can be the same or different and are hydrogen, C 1-30 -alkyl, C 2-30 -alkenyl, C 4-8 -cycloalkyl, C 5-8 -cycloalkenyl, aralkyl, aralkenyl or aryl, or R 1 is hydrogen, C 1-30 -alkyl, C 2-30 -alkenyl, C 4-8 -cycloalkyl, C 5-8 -cycloalkenyl, aralkyl, aralkenyl or aryl and R 2 and R 3 , together with the nitrogen of the amine of formula NR 1 R 2 R 3 form a 5- to 7-membered ring, whereby C 1-30 -alkyl, C 2-30 -alkenyl, C 4-8 -cycloalkyl, C 5-8 -cycloalkenyl, aralkyl and aralkenyl can be unsubstituted or substituted with NR 4 R 5 R 6 , imino, cyano, cyanamino, hydroxy and/or C 1-6 -alkoxy, and aryl can be unsubstituted or substituted with NR 4 R 5 R 6 , cyano, cyanamino, hydroxyl, C 1-6 -alkyl, and/or C 1-4 -alkoxy, wherein R 4 , R 5 and R 6 can be the same or different and are hydrogen, C 1-6 -alkyl, C 4-8 -cycloalkyl or aryl, and wherein the coating composition does not contain a dye or colour former.
