Abstract
Process for the preparation of disazo pigments of the formula ** (see formula) ** In which R1 means an alkyl, alkoxyalkyl or cycloalkyl group, containing from 1 to 6 carbon atoms, an aryl or aralkyl group, R2 means a hydrogen, bromine or especially chlorine atom, R3 represents a hydrogen atom, when r2 means a chlorine or bromine atom and r3 represents a carboxylic acid ester group, when r2 means a hydrogen atom, Z means a sulfur or oxygen atom, X means a hydrogen or halogen atom, an alkyl or alkoxy group, containing from 1 to 4 carbon atoms, a nitro, cyano, trifluormethyl group or an alkoxycarbonyl group, containing from 1 to 6 carbon atoms, Y denotes a hydrogen or halogen atom, an alkyl or alkoxy group, containing from 1 to 4 carbon atoms, a nitro, trifluoromethyl or cyano group, or an alkoxycarbonyl group, containing from 1 to 6 carbon atoms. Carbon or X and y signify a condensed bencan ring, characterized in that a diazo or diazoamine compound of an amine of the formula is coupled in a 2: 1 molar ratio ** (see formula) ** With a bis-acetoacetylphenylenediamine of the formula (see formula) (Machine-translation by Google Translate, not legally binding)
