[ We claim:] [1.] A one-component or two-component polyurethane coating composition comprising at least one reactive component capable of reacting with polyisocyanates, wherein the reactive component is a compound A) containing an isocyanate group, a urethane, thiourethane or urea group and two capped isocyanate-reactive groups, wherein the compound (A) is the addition product of 1 mol of a compound having the general structural formula [ STR 6 ] and one mol of diisocyanate, where R.sup.1 and R.sup.2 are, independently of one another, hydrogen or C.sub.1 -C.sub.10 -alkyl, X and Y are, independently of one another, oxygen, sulfur or an N-R.sup.6 group, R.sup.3 is C.sub.1 -C.sub.5 -alkylene and the heterocyclic ring can be substituted by further radicals R.sup.4 and R.sup.5, where one of the radicals R.sup.4, R.sup.5 or R.sup.6 must bear a group capable of reacting with isocyanate and is hydroxyl, mercapto, primary or secondary amino, or be such a group capable of reacting with isocyanate and the other radical R.sup.4, R.sup.5 or R.sup.6, if present at all, must contain no group capable of reacting with isocyanate, with the proviso that X is not oxygen when Y is N-R.sup.6, and Y is not oxygen when X is N-R.sup.6.
