Triphenodioxazine reactive dyes containing at least one fibre-reactive group, the dye, in the free acid form, having the formula:
wherein
each of T¹ and T², independently, represents H, Cl, Br, F, SO₃H or an optionally substituted alkyl or aryl radical;
each of A¹ and A² 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;
R¹ represents H or a group of the formula:
wherein
Z represents a fibre-reactive group;
each of R² and R³, 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
or R⁶(Q)a-
wherein
R⁴ represents H, an optionally substituted hydrocarbon radical free from fibre-reactive residues or an acyl radical;
R⁵ represents H or an optionally substituted hydrocarbon radical;
R⁶ 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.
