The present invention relates to coating materials with hydroxyl-containing polymers and di- and/or polyisocyanates, at least some of whose isocyanate groups are blocked with a mixture of from 30 to 85% by weight of one or more dialkyl malonates in which at least one of the ester radicals is an aliphatic, cycloaliphatic and/or araliphatic secondary alkyl radical having at least 3 carbon atoms and 70 to 15% by weight of at least one other dialkyl malonate. Preparation and the blocked polyisocyanates and coating materials and use of the coating materials is also provided.
