Abstract

1,129,849. Azo pigments. FARBENFABRI. KEN BAYER A.G. 27 Sept., 1967 [6 Oct., 1966], No. 44003/67. Heading C4P. Azo pigments free from sulphonic acid and carboxylic acid groups of formula in which K is a coupling component radical and the benzenes rings A may be substituted, e.g. by alkyl, alkoxy, nitro, or cyano groups or halogen, are prepared by reacting a compound with a coupling component K-H preferably in anhydrous inert organic solvents at 100‹ C. or above, e.g. chloro and nitro benzenes, naphthalene and p-chlorotoluene. The radical K is preferably a 2-hydroxy-naphthalene-3-carboxylic-acid arylamide or and aceto-acetic acid arylamide which may be substituted by halogen, nitro, alkyl, alkoxy or acylamino groups. Red pigments are obtained.
