Abstract

A process for the production of coatings based on reaction products of (A) polyhydroxy polyacrylate resins obtained from hydroxyalkyl esters of acrylic acid and/or methacrylic acid, alkyl acrylates and/or methacrylates, one or more polymerizable, olefinically unsaturated N-containing heterocyclic compounds and if appropriate vinyl-aromatics, acrylamides or methacrylamides and other monomers with (B) isocyanurate-containing polyisocyanates having a functionality of from 2.5 to 6 and predominantly containing cycloaliphatically bonded isocyanate groups is particularly useful for coating metal articles.
