    • Solid compositions containing diamidediurethanes are useful as components of hot-melt-inks. Diamidediurethanes may be prepared by reaction of a hydroxycarboxylic acid and/or lactone with either (1) monoamine and diisocyanate or (2) diamine and monoisocyanate. Alternatively, the diamidediurethane may be prepared by reacting a non-hydric carboxylic acid and/or anhydride with an hydroxyamine and a diisocyanate. The reactant identity and stoichiometry, as well as the reaction conditions, may be tailored to optimize the formation of diamidediurethane in preference to high molecular weight oligomers. The hot-melt inks may be used in ink jet, flexographic, gravure and intaglio printing.
    • 含有二酰胺二氨基甲酸酯的固体组合物可用作热熔油墨的组分。 二酰胺二氨基甲酸酯可以通过羟基羧酸和/或内酯与(1)单胺和二异氰酸酯或(2)二胺和单异氰酸酯反应来制备。 或者,二酰胺二氨基甲酸酯可以通过使非氢羧酸和/或酸酐与羟胺和二异氰酸酯反应来制备。 反应物特性和化学计量以及反应条件可以被调整以优化二酰胺二氨基甲酸酯优先于高分子量低聚物的形成。 热熔油墨可用于喷墨,柔版印刷,凹版印刷和凹版印刷。
