Abstract

1426053 Azo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 27 Feb 1973 [15 March 1972 21 Nov 1972] 12084/72 and 53694/72 Heading C4P [Also in Division D1] Dispensible azo dyestuff compositions are prepared by coupling, in the presence of 20 to 500% of the theoretical weight of the dyestuff of an anionic dispensing agent, an aqueous solution of a diazonium salt obtained by diazotisation of an amine free from water-solubilizing groups with an aqueous solution, suspension or emulsion of a coupling component free from water-solubilizing groups, if necessary adding further anionic dispensing agent until the amount is at least 100% of the theoretical weight of dyestuff and drying the suspension obtained. The suspension is preferably milled before drying. Diethylene glycol, glycol or urea may be added as humectants or antifreeze agents. The granular products are dispersed in water and the dispersions used to dye cellulose acetate, polyester and synthetic polyamide fibres.
