The present invention relates to a stabilized, aliphatic and/or cycloaliphatic, blocked polyisocyanates which have i) isocyanate groups blocked with CH-acidic esters, ii) a content of blocked isocyanate groups (calculated as NCO, MW 42) of 5 to 20, preferably 7 to 15 wt.%, based on the solids content of the blocked polyisocyanate and iii) a content of formaldehyde of 0.1 to 5 wt.%, based on the solids content of the blocked polyisocyanate. The present invention also related to a process for the preparation of these stabilized, blocked polyisocyanates and to their use in one-component polyurethane stoving compositions, which may be cured at relatively low stoving temperature of about 100°C, as crosslinking agents for organic polyhydroxy compounds.
