摘要:
New basic azo dyestuffs of the formula ##STR1## where D.sup.(+) is the radical of an aromatic or heterocyclic diazo component containing a quaternary nitrogen atom,A is an aromatic radical or, together with the -(NR)-member of the formula, forms a heterocyclic radical,R is hydrogen, optionally substituted lower alkyl, aralkyl or cycloalkyl,X.sup.(-) is an anion, andZ is hydrogen or methyl,Had been found which are suitable for dyeing and forming, for example, tannin-treated cellulose fibers, silk, leather, acetate silk, acid modified polyamide or polyester fibers and for dyeing and printing and spin-dyeing of polyacrylonitrile or polyvinylidene cyanide containing fibers. The dyeings and prints obtained are generally are of high tinctorial strength and brilliant and have very good fastnesses.

摘要:
Azo dyes of the formula WHEREIN D is carbocyclic or heterocyclic aryl, R is hydrogen or an organic radical, R1 is hydrogen, hydrocarbyl, heterocyclyl, amino or substituted amino, K is substituted ammonium or hydrazinium (including compounds wherein the nitrogen(s) is (are) part of a heterocyclic ring), and A is an anion. These azo dyes are useful for the dyeing and printing of fibers (and textiles thereof) of acrylonitrile polymers and copolymers as well as polyamides and polyesters containing acidic groups. They give level dyeings having good fastness to light and water.

摘要:
TRIAZOLIUM-AZO COMPOUNDS PRODUCE YELLOW TO RED DYEINGS, HAVING EXCELLENT FASTNESS TO LIGHT, ON ACRYLIC, MODACRYLIC AND ACID-MODIFIED TEXTILE MATERIALS AND HAVE A QUATERNIZED TRIAZOLYL DIAZO COMPONENT AND A 4-PHENYLTHIOMORPHOLINO-1,1-DIOXIDE COUPLING COMPONENT.
摘要:
THE DYE SOLUTION COMPRISES (1) AT LEAST ONE CATIONIC DYE, (2) PHOSPHORIC ACID OR AN ACIDIC PHOSPHORIC ACID ESTER AND (3) AT LEAST ONE WATER-SOLUBLE ORGANIC SOLVENT. THE SOLVENT IS A POLYOL OF THE FORMULA:
HO.R(G.R'')N.OH
WHEREIN R AND R'' DENOTE AN ALKYLENE GROUP HAVING 2 TO 3 CARBON ATOMS OR A 2-OXY-PROPYL GROUP, N DENOTES AN INTERGER WHICH IS ZERO TO 2 AND G DENOTES AN OXYGEN ATOM. WHEN N IS 1, G MAY ALSO BE A SULPHUR ATOM, A SULPHONYL GROUP OR A >N$COH GROUP; A LOWER ALKYL ETHER OF SAID POLYOL; DIMETHYL SULPHOXIDE; OR DIMETHYL FORMAMIDE.
