Aqueous binders and their use in aqueous coating compositions

摘要: The present invention relates to a process for preparing aqueous binders coating compositions by reacting mixture of A) 9.9 85 wt.% hydroxy- and acid-functional poly(meth)acrylate B) 14.9 90 hydroxy-functional, fatty acid-modified polyester with C) 0.1 20 diisocyanate having molecular weight 140 318, form urethane groups then dissolving or dispersing the reaction product in water prior simultaneous neutralization at least portion carboxyl present, wherein sum percentages add up 100. also obtained this their use, optionally combined other oxidatively drying lacquer resins, air- and/or heat-drying, two-component compositions, preferably polyurethane combination blocked polyisocyanates amino cross-linking agents heat-curing compositions.
