Abstract

The invention comprises vat dyes which contain an external hydroxyl group, that is a hydroxyl group which is bound through a bridge to a ring forming part of the nucleus of a vattable ring system, esterified by an organic acyl residue derived from a carboxylic or sulphonic acid and which acyl residue contains at least one sulphonic acid group. The dyes are made by acylation of a vat dye containing at least one suitable hydroxyl group with an appropriate acylating agent, halides being specified. Vat dyes specified are those of the anthraquinone, perylene tetracarboxylic acid diimide, naphthalene tetracarboxylic acid diimide, pyrene-quinone, indigo, thio indigo or cobalt phthalocyanine series. Examples illustrate dyes of the isodibenzanthrone, dibenzanthrone, acedianthrone, dianthraquinonylamino triazine, di(benzoylamino)-anthraquinone and perylene tetra-carboxylic acid diarylimide series. Acyl residues specified are derived from mono- or disulpho benzoic acids, benzene disulphonic acids, sulphofuroic acid, sulpho-thiophene carboxylic acid and sulpho-chloracetic acid. Examples are given. The dyes are generally water-soluble and may be vatted in alkaline hydrosulphite or even in glucose or sodium sulphide solutions at room temperature. They vat-dye and print natural and regenerated cellulose by the usual methods, the acyloxy groups being hydrolysed. Specifications 506,526, 512,512, 545,251, 607,956, 652,453, 859,283, 890,172 and 891,214 are referred to.
