Abstract

The invention comprises water-soluble disazo dyes of formula <FORM:0997639/C4-C5/1> wherein R1 is a p-phenylene or p-naphthylene residue free from hydroxyl groups, n is 1 or 2 and X is a halogenated pyrimidine or triazine nucleus. The dyes are prepared by condensing a di- or tri-halotriazine or an at least trihalogenated pyrimidine with an aminodisazo dye of the above formula but wherein X is a hydrogen atom. If cyanuric chloride is used in the condensation a second halogen atom in the dihalotriazine condensation product may be replaced by condensation with ammonia or with a primary or secondary amine. The dyes may be used to colour cellulose materials, particularly cotton, in the presence of an acid-binding agent in brown shades. In Examples: (1) and (2) the disazo dye aniline-2,5-disulphonic acid --> 1 - aminonaphthalene - 6 - sulphonic acid --> 1-aminonaphthalene is condensed with cyanuric chloride and the product condensed with an equimolar amount of ammonia; (3) the disazo dye aniline - 2,5 - disulphonic acid --> 1-aminonaphthalene --> 1-aminonaphthalene-8-sulphonic acid is condensed with 6-(31- or 21 - sulphoanilino)- or -(21,51 - disulphoanilino)- or -methoxy- or -phenoxy- or -phenylthio-2,4-dichloro - 1,3,5 - triazine; (4) the disazo dye aniline - 2,5 - disulphonic acid --> p-xylidine --> 1 - aminonaphthalene - 8 - sulphonic acid is condensed with 2,4,5,6-tetrachloropyrimidine. Further dyes are listed in a table. Specifications 797,946, 822,047, 838,337, 902,618, 904,581 and 916,094 also are referred to.
