摘要
A high strength aqueous solution comprising a first and second dye each of which, in the free acid form, is of Formula (1): CHEM wherein: R1 is NH2 or alkyl; W is H, alkyl or alkoxy; X is a labile atom or group; A is CHEM Y is H or alkyl; Z is an optionally substituted phenyl group; and n has a value of 1 to 3; provided that (i) the groups defined by A in the first and second dye are different to one another; and (ii) the solution contains less than 5% by weight of inorganic compounds. Also claimed are compositions and dyes of Formula (1).
