Abstract

1,195,886. Polyurethane stoving lacquers. FARBENFABRIKEN BAYER A.G. 30 June, 1967 [2 July, 1966], No. 30289/67. Heading C3R. [Also in Divisions B1-B2] A lacquer mixture comprises a masked polyisocyanate and a hydroxyurethane prepared by reaction between a polyhydroxy compound having a M.W. up to 800 and a deficiency of a polyisocyanate, the hydroxyurethane having a M.W. of 300 to 20,000. The hydroxyurethane is most suitably prepared by reacting a polyhydroxyalkylene compound, a low M.W. polyester or the reaction product of a polycarboxylic acid and an aminoalcohol with an alkylene or arylene polyisocyanate. Suitable masked polyisocyanates are the adducts of tolylene diisocyanate, trimethylolpropane, butylene glycol and phenol or of a trimerized tolylene diisocyanate and a cresol. Solvents for the lacquer mixture are suitably a ketone, ethylene glycol ether acetate, diacetone alcohol, cresol, dimethyl formamide, dimethyl acetamide and/or dimethyl sulphoxide.
