Abstract: The invention relates to a process for the preparation of a RMA crosslinkable composition comprising at least one crosslinkable component 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 and base catalyst C and one or more N—H group containing reactivity moderating component D that are also a Michael addition donor reactable with component B under the action of catalyst C, characterized in that the one or more reactivity moderating components D have a melting temperature above 60° C. and is first dissolved in one or more crosslinkable components comprising reactive components A or B and the obtained pre-dissolved product is later mixed with other components of the RMA crosslinkable composition.

Abstract: An RMA crosslinkable composition having at least one crosslinkable component including reactive components A and B each including at least 2 reactive groups, the at least 2 reactive groups of component A being 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) and a base catalyst (C) which reactive components A and B crosslink by Real Michael Addition (RMA) reaction under action of the base catalyst, characterised in that the at least one crosslinkable component including reactive components A and B in the composition have a total hydroxy number of less than 60, preferably less than 40 and more preferably less than 20 mg KOH/g solids. Further, specific resins A and B having a low hydroxy number for use in RMA cross-linkable compositions and a process for the manufacture thereof.
