Vinylsulphonyl class reactive dyes with a phthalocyanine and/or triphendioxazine chromophore

摘要

Phthalocyanine class reactive dyes of the formula <IMAGE> where a is 0 to 1, b is 0 to 1, m is 0 to 1, p is 1 to 6, q is 0 to 5, r is 1 to 6, the sum of a and b being one and the sum of p, q and r not exceeding 6, and Pc is an optionally substituted metal-free or metal-containing phthalocyanine radical, Tp is a triphendioxazine radical, R<1> is hydrogen, C1-C6-alkyl, phenyl or a radical of the formula L-SO2-Y, R<2> and R<3> are hydrogen, optionally substituted C1-C6-alkyl, phenyl or together with the nitrogen atom joining them together a heterocyclic radical, L is C2-C4-alkylene which is optionally interrupted by an oxygen atom in ether function, naphthylene or a radical of the formula <IMAGE> where U is hydrogen, hydroxysulphonylmethyl or hydroxysulphonyl and n is 1 or 2, X is oxygen, sulphur, carbonyl or a radical of the formula S(O)a, NR<1>, CO-NR<1> or NR<1>-CO-NR<1>, where a is 1 or 2 and R<1> is as defined above, and in the case of m being 1 the radical of the formula NR<1>-L-X may also be 1,4-piperazinediyl, Y is vinyl or a radical of the formula C2H4-Q where Q is a group which is detachable under alkaline reaction conditions, and M<(+)> is the equivalent of a cation, and also ...
