Zusammenfassung:	Liq. one-component PUR baking lacquer is based on (a) polymers contg. OH gps., with OH no. 10-300 mg KOH/g, (b) partly or completely blocked polyisocyanates based on isophorone diisocyanate, which contain uretedione gps., (c) organic Bi cpds. of formula (I), and (d) organic solvent(s), in amts. of 40-70 pts. wt. (a + b), 0.5-5 pts. wt. (c) and 30-60 pts. wt. (d) and 0.8-1.2 NCO equiv. of (b)/OH equiv. of (a); in which R = 1-16 C aliphatic hydrocarbyl. Also claimed is a method of producing the lacquer by reacting these components. Pref. in (I), R = linear or branched aliphatic hydrocarbyl. Polymer (a) has an OH no. of 25-150 mg KOH/g. The polyisocyanate (b) is chain-extended with glycols. The lacquer may also contain dye, filler, gloss enhancer, pigment, thermal, UV and oxidn. stabilisers and flow aid.
