Abstract

The present invention relates to binder compositions containing PA0 A) 40 to 95 parts by weight of OH-functional graft copolymer resins which are prepared by copolymerizing a mixture containing 0.1 to 10 parts by weight of at least one optionally functional polybutadiene having a molecular weight of 500 to 10,000 and having at least 20% by weight of side-chain 1,2-vinyl double bonds, and PA0 B) 5 to 60 parts by weight of a polyfunctional cross-linking resin selected from aminoplast resins and optionally blocked polyisocyanates, wherein the sum of the parts by weight of components A) and B) add up to 100, based on the weight of components A) and B). The present invention also relates to the use of the binder compositions according to the invention for lacquering vehicles, wood and furniture, and for preventing corrosion.
