摘要:
Dyestuff mixtures of(a) an anthraquinone dyestuff of the formula ##STR1## (b) a preferably blue azo dyestuff of the formula ##STR2## wherein R.sub.1 =H or halogen,R.sub.2 =alkyl,R.sub.3 =H or alkoxy, andR.sub.4 and R.sub.5 =alkyl or alkenyl, and(c), optionally, shading dyestuffs are particularly inexpensive and are distinguished by good dyebath stability and application properties.
摘要:
Mixtures of at least two different dyestuffs of the formulae ##STR1## in which the symbols have the meanings mentioned in the text represent a low-priced replacement for the known anthraquinone dyestuff Disperse Red 60.In the dyeing of mixed yarn, they are even superior with respect to sublimation fastness and cotton staining.
摘要:
Mixtures of dyestuffs of the formulae I to IV ##STR1## wherein the radicals have the meanings customary in dyestuff chemistry, are excellent substitute products for the expensive anthraquinone dyestuff Disperse Blue 56.
摘要:
Mixed crystals of dyestuffs of the formula I ##STR1## wherein R denotes alkyl andn denotes a number from 2 to 4, and dyestuffs of the formula II ##STR2## wherein R.sub.1, R.sub.2 and R.sub.3 denote alkyl, with a characteristic X-ray diffraction diagram are distinguished by a high tinctorial strength and liquor stability when they are used for dyeing polyester fibres.
