    摘要: Coating compositions suitable for stoved multi-layer coatings containing as binder:A) 20 to 40 wt. % of hydroxy-functional (meth)acrylic copolymer obtainable from styrene and/or styrene derivatives; hydroxyethyl, 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; (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 from hydroxyethyl, 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)alkyl residue 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, andE) 0 to 40 wt. % triazine-based components which crosslink with the hydroxyl groups of components A), B) and optionally C) to form ether and/or ester groups.
