Abstract
The present invention relates to a crosslinkable polymer composition comprising reactive components A and B each comprising at least 2 reactive groups wherein the at least 2 reactive groups of component A are acidic protons (C—H) in activated methylene or methine groups and the at least 2 reactive groups of component B are activated unsaturated groups (C═C) to achieve crosslinking by Real Michael Addition (RMA), wherein the component A is a malonate containing component and wherein components A and B react on drying of the crosslinkable polymer composition by deblocking of latent base catalyst C by evaporation of carbon dioxide, which latent base crosslinking catalyst, is a substituted carbonate salt according to formula 1 wherein Xrepresents a non acidic cation and wherein R is hydrogen, alkyl, aryl or aralkyl group.
