Abstract: Reactive dyes of the formula ##STR1## in which D is the radical of an organic dye of the monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide series, R is hydrogen or substituted or unsubstituted C.sub.1-4 -alkyl, A is a polymethylene radical having 2 to 6 C atoms (or its branched isomers) which can be substituted by chlorine, bromine, fluorine, hydroxyl, sulfato, acyloxy having 1 to 4 C atoms, cyano, carboxyl, alkoxycarbonyl having 1 to 5 C atoms or carbamoyl, or an alkyleneoxalkylene radical having 1 to 6 C atoms in each alkylene member, independently of each other; Y is a radical --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.

Abstract: A phthalocyanine compound of the formula:(R--X--).sub.m Pc(--Y--R.sup.1 --Z--).sub.n (--SO.sub.3 M).sub.p IwhereinPc is a phthalocyanine nucleus (Pc);eachR independently is a monovalent aromatic radical linked to a peripheral carbon atom of the Pc nucleus through X;X selected from S, Se and Te;m is 4 to 16;eachR.sup.1 independently is a divalent aromatic radical linked to two adjacent peripheral carbon atoms of the Pc nucleus through Y and Z;Y is selected from S, NT, Se and Te;Z is selected from S, Se, Te, NT and O;T is selected from H, alkyl and aryl;n is 0 to 7;M is H, a metal or optionally-substituted ammonium;andP is from 1 to 16.The compounds have a significant absorption band in the near infra red and depending on the number of sulphonic acids groups and the nature of the counter ion are soluble in aqueous and polar organic media.
