    摘要: Disperse dyes of the formula ##STR1## in which D is the radical of a diazo component, Y is a linear or branched, unsubstituted or substituted alkylene of one to four carbon atoms;R.sup.1 is hydrogen, optionally substituted linear or branched alkyl of one to four carbon atoms, optionally substituted cycloalkyl or aralkyl, phenyl, or a radical of the formula: ##STR2## and R.sup.2 is hydrogen or C.sub.1 to C.sub.6 alkyl which may bear chloro, bromo or cyano as a substituent; andD and the rings A and B may bear one or more further substituents other than --SO.sub.3 H and --COOH;and also to their productions and their use for dyeing water-repellent fibrous materials. The dyes are eminently suitable for dyeing hydrophobic fibers, particularly polyesters, in yellow to blue-green shades of excellent fastness properties.

    摘要: Anthraquinone dyes of the general formula: ##STR1## wherein R.sup.1, R.sup.3, R.sup.4 and R.sup.6 are selected from the group consisting of H, OH, OCH.sub.3, NO.sub.2, NH.sub.2 and NHCH.sub.3 ; R.sup.2 and R.sup.5 are selected from the group consisting of:(a) alkyl-, aryl-, alkaryl-, alkoxyaryl-, aminoaryl-, alkylaminoaryl-, dialkylamino-, arylaminoaryl- or ##STR2## wherein R.sup.7 is selected from the group consisting of alkyl-, aryl-, amino-, alkylamino-, dialkylamino-, arylamino-, alkyloxy-, and aryloxy radicals,along with their syntheses routes are disclosed. The dyes are particularly useful in liquid crystal displays which function with a "guest host" effect or in other electrooptical display devices having a medium therein switchable between different ordering states.
