The specification describes cellulose reactive unsymmetrical triphenodioxazine dyes of the Formula (1):
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 independently represents alkyl, alkoxy, Cl, Br, COOH, SO₃H or optionally substituted sulphamoyl;
each n independently has a value of 0, 1 or 2;
each m independently has a value of 1 or 2;
R¹ represents H or an optionally substituted hydrocarbon radical;
Q represents O or S;
x has a value of 0 or 1;
B represents an optionally substituted divalent hydrocarbon radical;
each of R² and R³, independently, represents H or an optionally substituted hydrocarbon radical or R² and R³ are joined together to form, with B and the two N atoms, a piperazine ring;
y has a value of 0 or 1, and
Z represents H, or an optionally substituted hydrocarbon radical or a fibre-reactive group;
provided that (1) at least one of R¹ and Z contains a fibre-reactive group; and (2) y is 0 when R¹ does not contain a fibre-reactive group.
