Abstract

1427904 Fibre-reactive azo dyestuffs BAYER AG 11 April 1974 [12 April 1973] 16122/74 Heading C4P [Also in Division C2] Novel azo dyes of formula (where one Y is H and the other a group-NRZ in which R is an optionally substituted C 1-6 alkyl group and Z is a fibre-reactive group; A denotes the radical of a coupling component) are prepared by reacting the corresponding dyes in which Y is a group-NHR with a compound X-Z where X is a substituent capable of being split off as an anion in the reaction. Alternatively the dyes are produced by diazotization and coupling. The dyes in which Y is a group -NH 2 are prepared by diazotizing 2-amino-1- sulpho-5- or 8-nitro-naphthalene, particularly a mixture of both compounds, and coupling with a compound A-H followed by reduction of the nitro group to amino. The preferred dyes are mixtures derived from the corresponding 5- and 8 - substituted - 1 - sulpho - 2 - amino naphthalenes. The dyes are used for colouring textile materials containing amide or hydroxy groups, particularly wool, silk, polyamide, polyurethane and cellulose.
