ABSTRACT:
Triisocyanates and isomeric mixtures of triisocyanates corresponding to the formula ##STR1## in which R represents hydrogen or an alkyl group having from 1 to 4 carbon atoms are made by phosgenating the corresponding triamine. These triisocyanates are particularly useful in the production of polyurethanes, especially polyurethane lacquer coats.
