ABSTRACT:
An unsymmetrical 1:2 chromium complex of a monoazo dyestuff and a disazo dyestuff which is non-fiber reactive and is free of sulfonamido and amino groups and which, in the form of the free acid has the formula: ##STR1## wherein A' is the radical of a 1-hydroxy-2-aminobenzene which is monosubstituted or disubstituted by chlorine, nitro, or sulfo, B' is a naphth-2-ol, resorcinol, p-(C.sub.1 -C.sub.6 -alkyl)-phenol, 1-phenol-3-methylpyrazol-5-one or acetoacetanilide radical, and the phenol group in the last two mentioned compounds can be substituted by C.sub.1 -C.sub.4 -alkyl C.sub.1 -C.sub.4 -alkoxy, chlorine or sulfo, K' is an unsubstituted or sulfo-substituted naphth-1-ol or naphth-2-ol radical, phenol which is substituted in the p-positioned by C.sub.1 -C.sub.6 -alkyl, an unsubstituted or sulfo-substituted 2-naphthylanime, and 1-phenol-3-methylpyrazol-5-one or an acetoactanilide radical, and the phenol group in the last two mentioned compounds can be substituted by C.sub.1 -C.sub.4 -alkoxy, chlorine or sulfo, and D' is the radical of a 1-hydroxy-2-aminobenzene or 1-amino-2-hydroxynaphthalene which is further substituted by nitro, sulfo or a mixture thereof.
These dyes do not contain any fiber-reactive groups and are useful for dyeing various natural or synthetic nylon materials. In particular, the present dyes are useful for dying wool and leather. These dyes have good color strength, are high-hiding and have good fastness to washing and perspiration.
