ABSTRACT:
The invention relates to coating compositions comprising:A) at least one low molecular weight reactive compound with a molecular weight (Mn) of 300–1,500 g/mol, preferably of 300–1,200 g/mol, with at least one secondary and/or tertiary amino group and at least two hydroxyl groups per molecule, which compound is obtained by reactingA1) at least one hydroxyalkyl ester of an olefinically unsaturated carboxylic acid with 2–12 C atoms in the hydroxyalkyl residue withA2) at least one lactone and withA3) at least one hydroxy-functional alkyl-, cycloalkyl- and/or alkoxyamine with at least one primary and/or secondary amino group per molecule and with 2–10 C atoms per molecule,B) at least one cross-linking agent with functional groups reactive towards active hydrogen and optionally,C) at least one binder with functional groups containing active hydrogen.
