Abstract
Stable tetrazomonoazo compounds are obtained by adding a suitable metal salt and/or an arylsulphonate to a solution of a tetrazo compound of the formula <FORM:0365759/IV/1> where R = a benzene or naphthalene nucleus, Y = an inorganic acid residue, and X = hydrogen, an alkyl, alkoxy or nitro group or a halogen, separating the precipitate and drying it. Diluents, e.g. salts, may be added. They are useful for producing black shades on the fibre and in substance by coupling with 2 : 3-oxynaphthoic acid arylides. In examples: (1) tetrazotized benzidine is coupled with a -naphthylamine (1 mol.), again diazotized and the tetrazo compound precipitated with aqueous zinc chloride and sodium chloride; o-anisidine or p-cresidine may be used instead of a -naphthylamine; (2) the tetrazo compound in (1) is precipitated with naphthalene-1 : 3 : 6-trisulphonic acid; (3) tetrazotized dianisidine is coupled with 3-amino-4-methoxy-1-methyl-benzene, again diazotized and precipitated as in (1); (4) tetrazotized m-mononitrobenzene is coupled with a -naphthylamine, again diazotized and the tetrazo compound precipitated as in (1). The p-aminodiaryl-p<1>-azoaryl-p-amino compounds of Specification 275,147, [Class 2 (iii), Dyes &c.], may also be tetrazotized and precipitated in a similar manner.
