Abstract:
The present invention provides coating compositions comprising (i) a) a compound containing a free carbonyl group and b) a nucleophile or (ii) a compound containing a free carbonyl group, which compound is substituted with one or more nucleophilic groups. The present invention also provides a process for the preparation of these compositions, substrates coated with these compositions and a process for their preparation, a process for preparing marked substrates using these compositions, and marked substrates obtainable by the latter process.
