    摘要: Waterinsoluble polyazo dyestuffs of the formulaX(O-OC-D-N=N-K).sub.mIn which K denotes identical or different radicals of a coupling component, X denotes an aliphatic radical which is free of hydroxyl groups and is optionally interrupted by heteroatoms, or an aromatic-carbocyclic, aromatic-heterocyclic or araliphatic radical, D represents an aromatic-carbocyclic or aromatic-heterocyclic radical and m represents the numbers 2 or 3. These dyestuffs are useful as dispersion dyestuffs for coloring synthetic fibers and most especially as pigment dyestuffs for coloring paint, inks, paper, and macromolecular substances and for admixing with other substances such as inorganic white pigments including titanium dioxide.

    摘要: Novel aromatic diamines having the general formula ##STR1## WHEREIN N IS AN INTEGER OF FROM 2 TO 8, X is sulfur or oxygen, and R is an n-valent hydrocarbon radical which may be interrupted by O or S atoms and which is obtained by removing OH or SH groups from a polyol or polythiol having a molecular weight of less than 600, are prepared by reacting a compound having the formula (HX).sub.n R where X, n and R are as defined above with about n-equivalents of an isatoic acid anhydride in the presence of a strong base. The aromatic diamines of the invention are particularly useful as the active hydrogen containing component for reaction with polyisocyanates in the preparation of synthetic resins by the isocyanate-polyaddition process.
