Abstract: Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers, in the swollen state, with a dye of the formula where X is hydrogen, chlorine, bromine, cyano, nitro, alkylsulfonyl of 1 to 4 carbon atoms, phenylsulfonyl, methoxy or ethoxy, Y is hydrogen, chlorine, bromine, cyano or nitro, Z is a radical of the formula Q is oxygen or sulfur, R1 is alkyl of 1 to 4 carbon atoms, methoxymethyl, phenoxymethyl or phenyl which is unsubstituted or substituted by chlorine, bromine, nitro, methyl, methoxy or ethoxy, R2 is hydrogen, methyl, ethyl, phenyl or phenyl substituted by chlorine, bromine or methyl, R3 is hydrogen, methyl or, if R2 is methyl, is C1 to C4 alkoxycarbonyl, R2 and R3 together with the linking carbon atoms are phenylene or phenylene substituted by chlorine, methyl, methoxy or ethoxy and K is a radical of a coupling component selected from the pyrazolone, pyrazole, indole, quinolone or homophthalimide series.

Abstract: Dye prepns. contain new azo dispersion dyes of formula (I). In (I), D is the gp. of a diazo component; Z1 and Z2 are gps. of formula NR1R2; Z3 is H, 1-7C alkyl or NR1R2; one of Z1 to Z3 is OR3; X is SO2R4 or CO2NR1R2; R1 to R4 are aliphatic, cycloaliphatic, araliphatic or aromatic gps.; R1 to R3 may also be H, and NR1R2 may be a satd. heterocyclic gp. Used for dyeing or printing of cellulose or cellulose-contg. textiles. Excellent fastness esp. to wet treatments and light is obtd., with no bleeding into white grounds of prints during washing.

Abstract: Water-soluble azo dyes of formula: (in which D is the gp. of a diazo component; X is CN or carbamcyl; n is 1-4; R is opt. substd. alkyl, cycloalkyl or aralkyl; the SO3H gps. are in substits. D and/or R) are used for dyeing or printing of natural or synthetic polyamides in yellow to violet shades. The cpds. give brilliant shades with excellent fastness.
