LACQUER BINDERS FOR LACQUERING PLASTICS

摘要

The present invention relates to new binder combinations comprising A) 99 - 30 parts by weight of OH-functional graft copolymer resins prepared by copolymerization of a polybutadiene having a molecular weight of from 500 to 10000 and containing more than 30 % of 1,2vinyl structure with selected olefinically unsaturated monomers and B) 1 to 70 parts by weight of a multifunctional crosslinking resin, preferably a polyisocyanate resin. The new binder combinations are suitable for preparing coatings having a very high level of elasticity and an excellent surface hardness.
