Abstract
The invention comprises dyes of formula : <FORM:0860279/IV(c)/1> where R is an alkyl or phenyl radical, one X is OH and the other H or OH, R1 is a benzene or naphthalene residue, n is O or 1, m is 1 to 4 and R1 is substituted #s to the azo bridge by OH or COOH and containing at least one SO3H group, and their metal complexes. The dyes are made by conventional processes from appropriate diazo components corresponding to R1 and ketonic coupling components with subsequent metallization if required. Metallization may be effected in substance or on the fibre. Specified coupling components are 2, 21, 4-and 2, 4, 41-trihydroxy- and 2, 21, 4, 41-tetra-hydroxy-benzophenone and 211, 21, 411, 41-tetrahydroxy-1, 4-dibenzoyl-benzene and butane. An example and a Table are provided illustrating the preparation of the dyes and their chromium and copper complexes and the use of both metal free and metallized dyes in the dyeing of wool and polyamide fibres and leather in various shades of red, brown, yellow and blue. Representative of the diazo components used in the Examples for mon-dis- and tetra-azo dyes are 1-amino-3-nitro-5-sulpho-and 1 -amino-5-sulpho-2-phenols, 2-carboxy-4-sulphoaniline and 1-amino-6-nitro-4-sulpho-2-naphthol.
