Abstract

The invention comprises azo dyestuffs, free from sulphonic acid groups, of the formula wherein the R’s are identical or different aromatic radicals, the X’s are identical or different substituents, A is a carbocyclic or heterocyclic radical and m is 0, 1, 2, or 3. They may be obtained by reacting a monoazo dyestuff of the formula or a functional derivative thereof, with a diamine of the formula H2N-A-NH2. Examples are given for the preparation of the dyes. They are useful for colouring plastics, lacquers and papers, and for the production of printing inks and pigment pastes. Monoazo dyes of Formula (II) or their functional derivatives are obtained by diazotizing optionally substituted 3-aminophthalic acids or their functional derivatives and coupling with 2-hydroxy-naphthoic acid-3-arylides, the components being free from sulphonic acid groups, and further reacting if necessary, to form the functional derivatives.ALSO:Polyvinyl chloride or grafted polymers of acrylonitrile-butadiene-styrene are coloured with azo dyestuffs free from sulphonic acid groups, of the formula wherein the R’s are identical or different aromatic radicals, the X’s are identical or different substituents, A is a carbocyclic or heterocyclic radical and m is 0, 1, 2 or 3. Examples are given in which it is stated that particular dyes may be incorporated into one of the above polymers.
