Abstract: There is disclosed a process for the preparation of 1-aminoanthraquinones from 5-nitro-1,4,4a,9a-tetrahydroanthraquinones with a basic reducing agent, which process is carried out under pressure in the temperature range above 100.degree. C. and in an aqueous-organic medium. The process affords very pure 1-aminoanthraquinone, which is, inter alia, an important intermediate.

Abstract: An inventive blue colorant comprising a chromophore having at least one hydroxy group-terminated polyester chain attached, through a suitable alkylamino linking group (or groups), to the 1- position, the 4- position, or both, of an anthraquinone backbone and having at least one hindering group in a secondary position in relation to said amino linking group is provided. Such colorants exhibit excellent amine/base stability and thermal stability, effective colorations, excellent low extraction rates, high lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain polyurethane substrates, and, most importantly excellent stability in the presence of excess of diisocyanates. The polyester chain or chains can be conveniently tailored to increase the solubility or compatibility in different types of polyurethane resin precursors thereby permitting the introduction of such excellent coloring chromophores within diverse polyurethane media and/or or diverse polyurethane substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such inventive colorants are provided as well as methods for producing such inventive colorants.

Abstract: Aminoanthraquinones are generally useful as dyes and coloring agents. But known methods of synthesizing unsymmetrically substituted 1,4-diaminoanthraquinones are tedious and complex. A simple and efficient method is provided for preparing 1,4-diaminoanthraquinones, particularly unsymmetrically substituted 1,4-diaminoanthraquinones, by means of novel monoamino-monotosyloxy-anthraquinones.
