Abstract

1382205 Aryl-quinazolone azo dyestuffs BAYER AG 12 June 1973 [13 June 1972] 27907/73 Heading C4P [Also in Division C3] Azo dyestuff free from sulphonic acid and carboxylic acid groups have the formula in which K is a radical of a coupling component, Ar is an aryl radical, and in which ring A optionally contains further substituents. K may be an acetaacetic acid aryl amide, a barbituric acid, an iminobarbituric acid, a 2,4-diamino-5-hydroxy-pyrimidine, a 2,4-dihydroxy-quinoline, a 5-aminopyrazole or a pyrazolone-(5) derivative. In particular the compounds have the formula in which the rings A and B opt. contain further. substituents. They are made by diazotization and coupling. The dyestuffs, when in pigment form, are suitable for the manufacture of compositions of very fast pigmentation, such as mixtures with macromolecular materials, paints, printing inks, or paper, and lacquers.
