    Abstract: The azo dyes of formula (I): (where K is the residue of a coupling component; R3 and R4 are independently H, Cl, Br, alkyl, alkoxy, nitro, cyano, alkylsulphonyl, arylsulphonyl, carboxyl, carbamoyl, sulphamoyl, N-substd. carbamoyl or N-substd. sulphamoyl, carbalkoxy or quinazolonyl opt. substd. by Cl, Br or NO2; R2 is H or CONHR' or SO2NHR; X is -O-N=C(R)-, -O-(R)C=N- or -N=C(R)O-; R is opt. substd. aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic gp; R' is H or as R; and providing that when the gp. -CONHR or -SO2NHR') are used as (a) fast yellow-red, solvent-insol. pigments for printing inks, paints and plastics such as PVC, when R is an aromatic gp. in (I) and K is the residue of a coupling component of the beta-naphthol, acetoacetarylide, pyrimidine, dihydroxyquinoline or dihydroxypyridine series, and for (b) light-fast dyeing of polyesters when R is an aliphatic gp. in (I) and the coupling components are of the cresol, N-alkyl-pyrimidine, N-alkyl-pyridine or N-alkyl-quinoline series.

    Abstract: Azo dyes. Cpds. of formula (I): (where A is anthraquinone, benzanthrone, anthrapyridone, anthrapyrimidine, pyrazolanthrone or thiazolanthrone derivs.; X is S or a -NH- bridge, and Y is a gp. which unites with the residue: to give a 5- or 6-membered ring which may itself contain (substd.) fused 5- or 6-membered rings; the benzene ring R may contain substits.). Preferably, cpds. (II): (where Z is orthophenylene, opt. contg. Me, MeO, carbonamide or sulphonamide gps., 1,2-naphthylene or one of the gps. -CH2-CH2-, -CH2-CH2CH2-, R1 is phenyl, benzoylamino or dimethylamino; R2 is H, Cl or OH; the ring E may contain Cl, benzoylamino or carboxylic anilide gps.). Used as pigment dyes, in print or varnish or for dyeing macromolecular materials, and have good colour fastness esp. towards solvents and light.
