    摘要: A process for the manufacture of modified N,N''-substituted 2,4,5-triketoimidazolidines which comprises reacting (a) at least one oxamidic ester having the group -NH-CO-CO-ORv wherein Rv is an aliphatic hydrocarbon group having up to 18 carbon atoms, a cycloaliphatic hydrocarbon group with up to 8 carbon atoms, a mononuclear aromatic hydrocarbon group having up to 14 carbon atoms, a mononuclear aromatic hydrocarbon group being substituted by one or more hydrocarbon groups having a total of up to 14 carbon atoms, (b) at least one isocyanate or isocyanate forming compound and (D) at least one compound selected from the group consisting of (d) an azomethine of formula (37) (cf. formula sheet), (e) a metal chelate of component (d), (f) an azo compound of formula (38), (g) a metal chelate component (f), (h) a combination of at least two of compounds (d) to (g) and, if desired, (c) a polycarboxylic acid, and a film, coating or shaped article prepared from said reaction product.
