Abstract
1,251,437. Mono-azo pigments. BADISCHE ANILIN- & SODA-FABRIK A.G. 11 March, 1969 [12 March, 1968], No. 12623/69. Heading C4P. The invention comprises mono-azo pigments of the general formula wherein ring A may be substituted by one or more chlorine or bromine atoms or methyl, ethyl, methoxy, ethoxy, carbamoyl, carbomethoxy, carboethoxy, cyano or nitro groups. They are prepared by coupling an optionally substituted diazotized aniline compound with 2,4-di-iminobarbituric acid. The pigments give yellow, orange and brown shades in paints, printing inks and plastics.
