    摘要: Blue anthraquinonoid disperse dyes are prepared by reacting a 1-amino-4-nitroanthraquinonecarboxamide (II) with a cyanide in an aqueous medium in the presence of hydroxyl ion acceptors at above 20.degree. C. by a process in which the reaction is carried out in water at a pH of from 7.5 to 10.5 and in the presence of one or more quaternary ammonium salts at from 60.degree. to 100.degree. C.The process gives disperse dyes which are similar to C.I. Disperse Blue 87 and have similar color properties in high yields by an environmentally compatible process, the said disperse dyes having excellent properties.

    摘要: A process for the preparation of pigmentary forms of perylene-3,4,9,10-tetracarboxylic acid diimide, wherein the diimide is converted to the leuco compound and the latter is oxidized in aqueous suspension, either with exposure to shearing forces in the presence of surfactants, or in the absence of shearing forces and in the presence of non-ionic surfactants, or of mixtures of non-ionic and anionic surfactants.The perylenetetracarboxylic acid diimide pigments give deep, brilliant and transparent full-shade colorations. In white reductions, they give distinctly reddish colorations.

    摘要: An .alpha.-indanthrone pigment having improved tinctorial and technological properties is produced by swelling .gamma.-indanthrone in sulfuric acid of from 73 to 80 percent strength by weight at from 20.degree. to 50.degree. C. in the presence of from 0.1 to 20% by weight, based on indanthrone, of a hydroxylammonium salt, a hydrazinium salt, amidosulfonic acid, urea, a salt of urea, formaldehyde or paraformaldehyde or a mixture of these. After precipitation in water which may or may not contain a surfactant, at below 50.degree. C., an .alpha.-indanthrone pigment of high tinctorial strength is obtained, which gives clear and pure colorations and is easily dispersible.
