    Abstract: MIXTURES OF MONOAZO DYESTUFFS OBTAINED BY COUPLING DIARZOTIZED ANILINE, WHICH MAY BE SUBSTITUTED BY LOWER ALKYL, LOWER ALKOXY, HALOGEN OR NITRO WITH A MIXTURE OF ONE OR TWO POLAR COUPLING COMPONENTS OF THE ACETOACETYLAMINO BENZENE, 1-ARYLPYRAZOLONE-(5) OR NAPTHOL SERIES CONTAINING 1 OR 2 CARBOXYLIC ACID, SULFONIC ACID, CARBOXAMINO OR SULFONAMIDO GROUPS AND ANOTHER MIXTURE CONSISTING OF ONE OR TWO UNPOLAR COUPLING COMPONENTS OF THE ACETOACETYLAMINOBENZENE, 1-ARYLPYRAZOLONE-(5) OR NAPHTHOL- SERIES WITHOUT ANY SOLUBILIZING GROUP. THE DYESTUFF MIXTURES SHOW IMPROVED REHOLOGICAL PROPERTIES AND AN IMPROVED TINCTORIAL STRENGTH. MOREOVER, THEY YIELD PURER SHADES AND HAVE AN INCREASED TRANSPARENCY.

    Abstract: Polyfunctional alcohols with at least two alcoholic hydroxy groups are effective agents for dispelling fog and clouds. Preferred solid compounds are the so called sugar alcohols, saccharides and polyvinyl-alcohol, as liquid compounds or compounds with a low melting point alkane-diols, -triols or polyols or their reaction products with oxalkylating agents. The said compounds are sprayed into fog or clouds in finely dispersed form. They may be used, optionally together with other fog and clouds dispelling agents.

    Abstract translation: 具有至少两个醇羟基的多官能醇是消除雾和云的有效试剂。 优选的固体化合物是所谓的糖醇，糖和聚乙烯醇，作为液体化合物或具有低熔点烷烃二醇，三醇或多元醇的化合物或其与烷氧基化剂的反应产物。 所述化合物以细分散形式喷雾成雾或云。 可以使用它们，可选地与其它雾和云消除剂一起使用。

    Abstract: Symmetrical and asymmetrical disazo compounds of the formula wherein K is the radical of an enolized or enolizable coupling component, Z is hydrogen, halogen, lower alkyl, lower alkoxy or nitro and N IS 1 TO 10 AND WHEREIN AN ASYMMETRY CAN BE CAUSED BY A DIFFERENT POSITION OF THE SUBSTITUENTS ON THE BENZENE RINGS A and B and/or by different substituents Z and/or different coupling component radicals K, and mixtures of such compounds are colorants, especially pigments, of a high tinctorial strength and purity of shade, good rheological properties in lacquers and printing inks, high luster of colorations, good fastness to light, solvents, alkali, acids and migration, combined with a good covering power. Especially the combination of good covering power and high tinctorial strength is advantageous for lacquers and printing inks.

    Abstract: Symmetrical and asymmetrical disazo compounds of the formula: +TR wherein: the R1's are identical or different and are hydrogen, chlorine, bromine, methyl or methoxy; the R2's are hydrogen, or, if the R1's are hydrogen, the R2's are hydrogen, methyl or ethyl, the two R2 radicals being identical or different; and n is 1 to 4 and mixtures of such compounds as colorants, especially for pigmenting high molecular weight organic material. These compounds display high tinctorial strength, high fastness to light, and very good stability to heat, making them outstandingly suitable for dyeing and printing plastics, natural and synthetic resins, rubber, paper, viscose, cellulose, cellulose esters, cellulose ethers, polyvinyl chloride, polyamides, polyolefins, halogenated polyolefins, polystyrene, polyurethanes, polyacrylonitriles, polyglycol terephthalates or copolymers based on acrylonitrile/butadiene/styrene (ABS copolymers) and also for the preparation of printing inks, colored lacquers and emulsion paints and for pigmenting printing pastes for graphical and textile printing and printing on plastic and metal surfaces.
