Abstract

Curing component (A) based on polyisocyanates for binders (B) which contain groups containing active hydrogen, wherein the curing component (A) is a product of the reaction of (a1) polyisocyanates with (a2) .alpha.-hydroxyalkylpyridines. Mixtures of (A) and (B), and also, if appropriate, diluents (C) and additives (D), are stable on storage and give, even at temperatures of 120.degree.-140.degree. C., curing products which are sufficiently solvent-stable. They are suitable, in particular, for surface-coating preparations.
