Abstract
1466299 Tetrakisazo pigments CIBA-GEIGY AG 21 June 1974 [21 June 1973] 27601/74 Heading C4P Novel pigment dyestuffs of the formula (wherein A is naphthylene or X is H, halogen, C 1-4 alkyl or alkoxy, NO 2 or esterified carboxyl; Y is H, halogen or C 1-4 alkyl or alkoxy; X 1 is H, halogen, C 1-4 alkyl, alkoxy or alkanoylamino, NO 2 , CN, CF 3 , esterified carboxyl, or optionally substituted phenoxy or aroylamino the substitution being selected from halogen and 1-4 C alkyl and alkoxy;. X 2 and X 3 are each H, halogen, C 1-4 alkyl or alkoxy, NO 2 , CF 3 or esterified carboxyl, and Y 1 , Y 2 , Y 3 and Y 4 are each H, halogen, C 1-4 alkyl or alkoxy, NO 2 , CN, CF 3 or C 2-6 alkoxy carbonyl) are prepared by coupling a. diazo or diazoamino compound of an amine of the formula with a compound of the formula Coupling may for example be effected by combining an acid solution of the diazonium salt (one example of which contains N-benzyl-Á- heptadecyl benzimidazole disulphonic acid and acetic acid) with an alkaline solution of the coupling component in a mixing jet; or by a normal coupling procedure effected in the presence of a wetting agent such as n-butyl sulphoricinoleate; or by coupling in a solution prepared using t-butyl nitrite in glacial acetic acid and dichlorobenzene. The dyestuffs are used for pigmenting high molecular weight organic material, e.g. PVC, and may be used for example in printing inks and varnishes, e.g. linseed oil varnishes, generally following aftertreatment by heating with organic solvents, e.g. orthodichlorobenzene.
