Zusammenfassung:Polyisocyanates blocked by means of blocking agents composed of A) from 30 to 70 equivalent-% of diisopropylamine, B) a total of from 30 to 70 equivalent-% of at least one other blocking agent selected from the group consisting of CH-acidic esters and 1,2,4-triazole and C) from 0 to 20 equivalent-% of other blocking agents, a process for their preparation by blocking organic polyisocyanates using such blocking agents, and their use as crosslinking agents for organic polyhydroxyl compounds in polyurethane bake finishes (stoving enamels, lacquers, paints, varnishes).
