A process for printing an image on a substrate comprising applying thereto a composition comprising a liquid medium and a tris-azo compound of Formula (1) or salt 5 thereof: wherein: A is an optionally substituted alkenyl, homocyclic or heterocyclic group; L' and L2 are each independently optionally substituted aryl or heteroaryl; and m and n are each independently 0 or 1 such that m+n is 1 or 2; wherein: (i) the compound of Formula (1) is optionally in the form of a metal chelate; and (ii) at least one of L1 and L2 carries at least one substituent selected from sulpho, carboxy, C1.4-alkoxy and C1-4-alkoxy-OH. Also claimed are compositions and compounds comprising Formula (1).
Azo dyes of the formula ##STR1## in which D is the sulfo group-containing radical of an aromatic or heterocyclic diazo component, which can be further substituted and itself can contain an azo bridge, R.sub.1 and R.sub.2 independently of one another are each a hydrogen atom or a substituted or unsubstituted alkyl or aryl radical and X is a substituted or unsubstituted alkyl or alkenyl radical, and their heavy metal complexes, it being possible for the azo dyes of the formula (1) and their heavy metal complexes to contain reactive radicals.
