<p>Triphenodioxazine reactive dyes containing at least one fibre-reactive group, the dye, in the free acid form, having the formula: <CHEM> wherein each of T<1> and T<2>, independently, represents H, Cl, Br, F, SO3H or an optionally substituted alkyl or aryl radical; each of A<1> and A<2> represents alkyl, alkoxy, Cl, Br, COOH, SO3H or optionally substituted sulphamoyl; n has a value of 0, 1 or 2; m has a value of 1 or 2; R<1> represents H or a group of the formula: <CHEM> wherein Z represents a fibre-reactive group; each of R<2> and R<3>, independently, represents H or an optionally substituted hydrocarbon radical; B represents an optionally substituted divalent hydrocarbon radical; and D represents a group of the formula <CHEM> or R<6>(Q)a- wherein R<4> represents H, an optionally substituted hydrocarbon radical free from fibre-reactive residues or an acyl radical; R<5> represents H or an optionally substituted hydrocarbon radical; R<6> represents H or an optionally substituted hydrocarbon radical free from fibre-reactive residues; Q represents O or S; and a has a value of 0 or 1, with the proviso that when D is NH2, B is an arylene radical.</p> |
