摘要:
Disperse dyestuffs of the formula ##STR1## wherein Z represents an optionally substituted hydrocarbon radical,The azo group is in the meta-position or para-position relative to the amino group of the disphenylamine and the radical --OSO.sub.2 Z is in the ortho-position or para-position relative to the azo group.The rings A, B and D can be further substituted.The dyestuffs are suitable for dyeing synthetic fibre materials, especially polyesters, which are dyed in yellow to orange-red shades of good tinctorial strength and with good fastness properties in use, such as, for example, fastness to light and wet processing.
摘要:
A recording liquid is characterized by containing as a dye a compound represented by the formula ##STR1## wherein R.sub.1 represents hydrogen or C.sub.1 -C.sub.2 alkyl, R.sub.2 and R.sub.3 each represent hydrogen, C.sub.1 -C.sub.2 alkyl, or C.sub.1 -C.sub.2 alkoxy, R.sub.4 and R.sub.5 represent hydrogen or sulfo in salt form with base, and Q.sub.1 represents naphthyl substituted by hydroxyl and by sulfo in salt form with base.
摘要:
Disclosed are azo dyes containing, a diazo component radical of the formula ##STR1## wherein each of Z and Z.sub.1 is independently hydrogen or sulfo, with the proviso that at least one of Z and Z.sub.1 is hydrogen, for example monoazo and disazo dyes of the formula ##STR2## and salts thereof, wherein K is a coupling component radical of the aromatic carbocyclic, active methylene group-containing aliphatic or aromatic heterocyclic series, andZ and Z.sub.1 are as defined above, with the proviso that the dyes contain one or two sulfo groups, and the use thereof for the dyeing and printing of anionic dyeable substrates, particularly polyamide substrates.
摘要:
in which D is the radical of a diazo component; E is hydrogen, unsubstituted or substituted alkyl or phenyl; Z is cyano or carbamoyl; R is hydrogen or an unsubstituted or substituted aliphatic, araliphatic, cycloaliphatic or aromatic radical or two radicals R together with the nitrogen atom form a saturated heterocyclic ring; and N IS 1, 2 OR 3. The dyes are eminently suitable for dyeing natural and synthetic polyamides and give bright yellow to violet colorations having excellent fastness properties. Azo acid dyes which contain one, two or three water-solubilizing sulfo groups and which, in the form of the free acids, correspond to the formula (I):
