    • The present invention relates to binder compositions containingA) 40 to 95 parts by weight of OH-functional graft copolymer resins prepared by copolymerizinga) 0.1 to 10 parts by weight of polybutadienes containing at least 20% of 1,2-vinyl groups,b) 5 to 30 parts by weight of aliphatic .alpha.-olefins,c) 0.1 to 35 parts by weight of glycidyl esters of .alpha.-alkylalkane-monocarboxylic acids,d) 10 to 70 parts by weight of unsaturated, aromatic monomers,e) 5 to 60 parts by weight of hydroxyalkyl esters of acrylic and/or methacrylic acid having primary hydroxyl groups,f) 0 to 50 parts by weight of (cyclo)aliphatic esters of acrylic and/or methacrylic acid,g) 0.1 to 20 parts by weight of .alpha.,.beta.-mono-olefinically unsaturated monocarboxylic or dicarboxylic acids and/or maleic acid or fumaric acid semi-esters andh) 0 to 30 parts by weight of other copolymerizable compounds andB) 5 to 60 parts by weight of polyfunctional crosslinking resins,wherein 1 to 30% by weight of the OH groups of the component A) are secondary OH groups. The present invention also relates to the use of these binder compositions for vehicle coatings, in particular automotive refinish coatings and large vehicle coatings, for wood and furniture coatings, general industrial coatings, and for coatings that provide corrosion protection.
