    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):

    wherein:

    R¹ is NH₂ or alkyl;
    W is H, alkyl or alkoxy;
    X is a labile atom or group;
    A is

    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).
