Abstract: The novel azo pigments are of formula(I): (where D is the residue of a diazo or tetrazo component; n= 1 or 2; X = O or NH; the ring A may be further substd.). Pref. cpds. have the ring A unsubstd., D being derived from halo-anilines, aminobenzene carboxylic acid esters and -amides or from trifluoromethyl aniline or dichlorobenzidine. For colouring printing pastes, lacquers such as acrylate resin-, melamine resin- and polyester resin lacquers, and plastics such as polystyrene, PVC, polyolefins, rubbers and plastics dispersions yellow-orange shades which are partially light fast and bright.

Abstract: Azo pigments of formula (I): (in which D is the gp of a diazo component, and R is H or an aromatic or heterocyclic gp.). The pigments are useful in printing inks, paints or plastics, e.g. PVC, giving orange-red to bluish-red shades. They are very insoluble and exhibit good fastness to light, overpainting and migration.

Abstract: The pigments are of formula (in which R1 is hydrogen or alkyl; X is hydrogen, chlorine or bromine; R2 and R3 are hydrogen, chlorine, bromine, alkyl, alkoxy, alkyl sulphonyl, carbamoyl, sulphamoyl, or N-substd. carbamoyl or sulphamoyl; and R4 is cyano or carbamoyl). X is pref. Cl or Br.R1 is hydrogen, R2 is Cl, Br, CH3, OCH3, methyl sulphonyl or N-substd. carbamoyl and is adjacent to the acylamino gp. R3 is hydrogen, or Cl or CH3 in p-posn. to R2 and R4 is cyano. They have high brilliance and extremely strong covering power, being suitable for colouring plastics, printing inks or paints in orange to red-violet shades.

Abstract: Azo pigments having 2,6-dihydroxy-4-methyl-3-cyanopyridine or 2,6-dihydroxy-4-methyl-3-carbamolpyridine as coupling component and a heterocyclic substituted aniline as diazo component. The pigments have the formula IN WHICH R is cyano or carbamoyl; A is an unsubstituted or substituted benzene ring; and B is a heterocyclic ring which is fused with the benzene ring and which contains at least one -NH- and -CO- or at least one -NH-CO- group. Compounds of this formula as pigments are eminently suitable for coloring printing inks, surface coatings and resins.
