摘要：Coating compositions suitable for stoved multi-layer coatings containing asbinder:

A) 20 to 40 wt. % of hydroxy- functional (meth)acrylic copolymer obtainable fromstyrene and/or styrene derivatives; hydroxyethyl, hydroxypropyl and/or hydroxybutyl(meth) acrylate; non-functionalised (cyclo)alkyl (meth)acrylates having 8 to less than 18 Catoms in the (cyclo)alkyl residue; (meth)acrylic acid and optionally non-functionalised(cyclo)alkyl (meth)acrylates having up to 7 C atoms in the (cyclo)alkyl residue;

B) 20 to 40 wt. % of hydroxy-functional (meth)acrylic copolymer obtainable fromhydroxyethyl, hydroxypropyl and/or hydroxybutyl (meth)acrylate; non- functionalised(cyclo)alkyl (meth)acrylates having 8 to less than 18 C atoms in the (cyclo)alkyl residue;non-functionalised (cyclo)alkyl (meth) acrylates having up to 7 C atoms in the (cyclo)alkylresidue and (meth) acrylic acid;

C) 0 to 40 wt. % of hydroxy-functional binders other than A) and B),

D) 10 to 50 wt. % of free or blocked polyisocyanates, and

E) 0 to 40 wt. % triazine-based components which crosslink with the hydroxyl groupsof components A), B) and optionally C) to form ether and/or ester groups.
