Abstract
1,168,944. Monoazo pigments. CIBA Ltd. 6 March, 1968 [6 March, 1967; 2 Feb., 1968], No. 10908/68. Heading C4P. [Also in Division C3] The invention comprises monoazo pigments of the general formula wherein R 1 is a diazo component residue, R 2 is a naphthostyryl residue and Y is H, halogen, cyano, or alkoxy. Preferred diazo components have the general formula wherein X is H, halogen, alkyl, alkoxy, nitro, carboxylic acid ester or optionally substituted phenoxy group, A is -CONH- ortho, or parato the amine group and aryl stands for a benzene, naphthalene or p-diphenyl residue which may be substituted. They are prepared by (a) condensing a monoazonaphthoic acid chloride with an aminonaphthostyryl, or (b) coupling a diazo component R 1 NH 2 or a diazoamino compound containing the R 1 radical with an appropriate naphthol containing a -CONHR 2 in the 3-position. Coupling may take place in presence of dimethyl formamide and the products may be after-treated by boiling in nitrobenzene. The monoazonaphthoic acid chloride may be prepared from the corresponding carboxylic acid by reaction with thionyl chloride. The pigments may be used to colour viscose, cellulose ethers or esters, polyamides, polyurethanes, polyesters, lacquers, lake formers, cellulose acetate, nitrocellulose, aminoplasts, phenoplasts, alkyd resins, polystyrene, polyethylene or propylene, P.V.C., polyacrylonitrile, rubber, casein and silicones.
