    Abstract: Anthraquinoid acid dyes of the formula

    IN WHICH ALK IS A LINEAR OR BRANCHED ALKYLENE OF 1 TO 3 CARBON ATOMS, R1 and R2 are hydrogen or alkyl of 1 to 12 carbon atoms or cycloalkyl of 5 to 10 carbon atoms (which may bear alkoxy or alkylthio as a substituent), or the group -NR1R2 is a five-, sixor seven-membered saturated heterocyclic ring, R is a divalent mononuclear or binuclear aromatic radical in which 1 to 4 hydrogens may be replaced by alkyl, alkoxy or alkylthio of 1 to 4 carbon atoms and/or halogen, and n is one of the integers 1 and 2. The ring B may bear 1 or 2 chlorine atoms or hydroxy groups. The dyes dye nitrogenous fibers, especially polyamide fibers, clear blue shades having good fastness properties.

    Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein perylene-3,4,9,10-tetracarboxylic acid N,N'-bis-(2',6'-dichlorophenyl)-diimide is employed as the charge carrier-producing dye, and the production of this recording medium.

    Abstract: A process for converting a crude, coarsely crystalline perylene-3,4,9,10-tetracarboxylic acid diimide of the formula where A is unsubstituted or substituted phenyl, an unsaturated 5-membered or 6-membered heterocyclic ring which contains one or two nitrogen atoms and may be fused to a benzene nucleus, C3-C6-alkyl, or C2-C3-alkyl which is substituted by C1-C4-alkoxy, phenyl or C-acylamino, to a pigmentary form, wherein the crude pigment, in aqueous suspension, is comminuted in a high-speed mill in the absence of a surfactant. The pigments obtained give pure shade colorations of high to extremely high hiding power, and have a high tinctorial strength in white reductions.

    Abstract: 1,142,027. Anthraquinone dyestuffs. BADISCHE ANILIN- & SODA-FABRIK A.G. 9 June, 1966 [10 June, 1965], No. 25721/66. Heading C4P. The invention comprises compounds of the formula A-NH-B, where A denotes the radical of a 1.amino.anthraquinone-2-sulphonic acid and NH 2 -B denotes a monoamine or diamine of a dihydro or tetrahydro compound of a dimeric or trimeric cyclopentadiene an amine group of which is connected to a carbon atom of A. The compounds are prepared by reacting a compound of the formula NH 2 -B with a halo-1-amino-anthraquinone-2-sulphonic acid. A 4-halo derivative is preferably used.

    Abstract: The invention comprises anthraquinone dyestuffs of the general formula in which Y is hydrogen or a group where in X is -0-, -S- or -NR-; Y1 is hydrogen, hydroxyl, amino which may be substituted, or when Y is hydrogen, Y1 is a group as defined above; R is hydrogen, an aliphatic radical which may be substituted, an aromatic group which may be substituted, or an acyl group, and the rings A, B and C may bear substituent groups othr than sulphonic acid groups. They may be prepared by reacting a compound of general formula wherein Z is a hydrogen atom or a radical which can be exchanged for a group as defined above and Z1 is hydrogen, hydroxy, amino, substituted amino or when Z is hydrogen Z1 is a group as defined above with a compound wherein C and X are as defined above in presence of a solvent and an acid binding agent. Any sulphonic acid groups in rings A and B are eliminated by reaction with sodium dithionite and sodium carbonate in aqueous solution. Specified solvents are C1-C4 alcohols, acetone and methylethyl ketone, 2-methoxyethanol and 2 ethoxyethanol. Examples of acid binding agents are sodium and potassium hydroxides, carbonates and bicarbonates, calcium and magnesium hydroxides, carbonates, trisodium phosphate and alkali metal acetates. Many examples are given and among the compounds claimed per se are (i) (ii) (iii) (iv) (v)
