    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: Solid pigment formulations containing from 70 to 97% by weight, based on the total weight of the formulation, of one or more pigments and also from 3 to 30% by weight, based on the total weight of the formulation, of at least one surfactant which is an adduct of ethylene oxide and optionally propylene oxide with ethylenediamine, the proportion of ethylene oxide being from 46 to 100% by weight, based on the total weight of ethylene oxide and propylene oxide in the adduct, and the adduct having an average molecular weight of from 5000 to 40,000, are useful for pigmenting printing ink and gloss paint compositions.
