    摘要： The present disclosure is concerned with solvent free or very low solvent coating compositions suitable for use on flexible sheet form substrates particularly textile substrates. The composition comprises a urethane group-containing prepolymer with OH or CONH.sub.2 terminal groups mixed with a urea or melamine formaldehyde resin and a stable aqueous polymer dispersion or solution. The composition may also contain small amounts of an organic solvent. The coating can be applied to the substrate by direct or reverse coating techniques.

    摘要： The present invention relates to a process for preparing pure bis(isocyanatoalkyl)monouretdiones corresponding to formula (I) ##STR1## wherein R represents identical or different, linear or branched alkyl groups having 4 to 9 carbon atoms, by oligomerizing at least a portion of the isocyanate groups of aliphatic diisocyanates in the presence of catalysts which accelerate the dimerization of isocyanate groups, terminating the reaction at the desired degree of oligomerization, removing unreacted excess diisocyanate by extraction or thin film distillation to obtain a distillation residue, subjecting the distillation residue to thin film distillation at a temperature of 160.degree. to 220.degree. C. and a pressure of 0.01 to 1.0 mbar and obtaining bis(isocyanato-alkyl)monouretdiones corresponding to formula (I) as the distillate.
