Abstract: Described herein are a curable coating composition including at least one Michael donor (A) having at least one thiol group, at least one Michael acceptor (B) and at least one specific catalyst (C), a method of using the curable coating composition as a clear coating in a process to prepare a multilayer coating and a multilayer coating obtained from said process. Also described herein is a kit-of-parts including at least two separate containers C1 and C2, where the specific catalyst (C) is contained in container C1 and/or C2. Finally, described herein is a method of using specific salts of carboxylic acids as catalyst in a reaction between a Michael donor (A) having at least one thiol group and a Michael acceptor (B).
