    摘要: Printing inks are described which utilize a unique class of coloring agents which are the reaction products of free NCO group bearing resins and dyestuffs bearing reactive hydrogens. A novel class of such adducts which contain monocarboxylic acid residues are also described. These printing inks, which may also contain traditional pigments, find particular utility in letterpress or offset printing.
