<p>A PROCESS FOR THE PRODUCTION OF COATINGS The invention relates to a process for the production of coatings using a coating composition containing as binder optionally blocked lacquer-grade polyisocyanates in combination with polyhydroxy polyacrylate resins based on copolymers of certain hydroxy alkyl(meth)acrylates, methyl methacrylate, 2-ethylhexyl acrylate and, optionally, (meth)acrylic acid, wherein the molecular weight is in the range from about 30,000 to 80,000, the content of low molecular weight constituents having molecular weights of at most about 3000 amounts to between 3 and 15% by weight, the molecular heterogeneity factor amounts to between about 1.0 and 10.0, and the parameter for the chemical heterogeneity of the copolymer is between 0 and about 0.06.</p> |
