Abstract
The invention comprises azo dyestuffs which, in the form of the free acid, have the formula <FORM:1119276/C4-C5/1> wherein R represents a disulpho- or trisulphopyrene residue and Y represents a fibre-reactive substituent. They may be obtained by (1) condensing a dye of the formula <FORM:1119276/C4-C5/2> with an organic compound containing an exchangeable atom or grouping, which compound is capable of reacting with a primary or secondary amino group with formation of a fibrereactive group; or (2) first 1,3-phenylene-diamine-4-sulphonic acid is condensed with the said organic compound and the condensation product coupled with a diazo compound obtained from an aminopyrene-di- or tri-sulphonic acid. Y is preferably a heterocyclic halogenated residue containing 2 or 3 nitrogen atoms. Examples are given for the production of the dyes. They may be used for dyeing and printing a variety of organic materials red shades.
