Salts of black trisazo dyes with alkyl amines having good solubility in organic liquids

Abstract

Black compounds of Formula (1) having enhanced solubility in polar organic liquids which are useful as ink colorants in conventional and hot melt ink-jet printing and automatic identification, as black colorants for toners and thermal wax transfer sheets and as charge control agents for electrophotographic toners; ##STR1## wherein R is H, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, aryl, C.sub.4-8 cycloalkyl, --CN, --NO.sub.2, halogen, --COOR.sup.1, --OH, --SH or --SO.sub.3 A; R.sup.1 is A, C.sub.1-4 -alkyl or aryl; R.sup.2 is --NH.sub.2, --OH or --SO.sub.3 A; R.sup.3 is --NH.sub.2 or --OH; R.sup.4 is --NH.sub.2, --OH, --SO.sub.3 A or H; and A is NQ.sub.4 in which at least one Q is a branched chain fatty C.sub.6-20 -aliphatic group.
