ABSTRACT:
The invention is directed to coating compositions comprising:A) 20–80 wt-% of at least one orthoester compound having at least one non-cyclic orthoester group and at least one hydroxyl group per molecule, which compound is obtained by reactinga) at least one orthoester compound withb) at least one diol with a number average molecular weight (Mn) of 200–1000 g/mol, wherein solely diols are used having hydroxyl groups with different reactivity and having more than 3 carbon atoms between the hydroxyl groups,B) 0–40 wt-% of at least one hydroxy-functional binder and/or hydroxy-functional reactive diluent, different from component A) andC) 80–20 wt-% of at least one cross-linking agent with functional groups reactive with hydroxyl groups.
