3 Metallisable trisazo black dyestuffs and mixtures thereof, their preparation and use in dyeing cellulosic fibres EP80302157.5 1980-06-26 EP0021837A1 1981-01-07 Smith, Howard L.

Water-soluble trisazo compounds useful as developed direct black dyes for cellulosic textiles and as self-shade dyes for paper and leather; imparting a black coloration thereto. The compounds have the structure: wherein R' is: and M is H, Na, K, Li, N(R)3H where R is H, lower alkyl or lower hydroxyalkyl and each of the R groups can be the same or different The compounds are intended to replace dyes synthesized from an intermediate (benzidine) whose use is being curtailed as a known carcinogen.
