An asymmetric dioxazine compound represented by the following formula (I) in the free acid form: ##STR1## wherein A.sub.1 and A.sub.2 independently of one another are each sulfo, halo, alkyl or alkoxy, X.sub.1 and X.sub.2 independently of one another are each hydrogen, halo, alkyl, alkoxy or phenoxy, R.sub.1 is hydrogen or unsubstituted or substituted alkyl, R.sub.2 and R.sub.3 independently of one another are each hydrogen, alkyl, alkoxy, halo or unsubstituted or substituted amino, Z is a fiber-reactive group, m and n independently of one another are each 0 or 1, provided that m.noteq.n, and L is 1 or 2. This compound is suitable for dyeing and printing cellulose fiber, natural and synthetic polyamide fibers, polyurethane fiber, leather and the like and mixed yarns thereof, to obtain dyed or printed products of a color fast to light, wetness and chlorine with superior build-up and level dyeing properties.

Asymmetric dioxazine compounds and method for dyeing or printing fiber

A dioxazine compound represented by the following formula in the free acid form, ##STR1## wherein V is a direct linkage or ##STR2## in which R.sub.3 is hydrogen or alkyl, X is a direct linkage or an aliphatic, araliphatic or aromatic bridging group, Y is phenylene or naphthylene, Z is a so-called vinylsulfone type fiber reactive group, and R.sub.1 and R.sub.2 are each hydrogen or alkyl, which is useful for dyeing or printing fiber materials to give a dyed or printed product of a blue color superior in fastness properties with superior build-up property.

Dioxazine blue dye compound having vinylsulfone type fiber reactive

An asymmetric dioxazine compound represented by the following formula (I) in the free acid form: ##STR1## wherein A.sub.1 and A.sub.2 independently of one another are each sulfo, halo, alkyl or alkoxy, W is an unsubstituted or substituted aliphatic or aromatic bridging group, X.sub.1 and X.sub.2 independently of one another are each hydrogen, halo, alkyl, alkoxy or phenoxy, R.sub.1 and R.sub.2 independently of one another are each hydrogen or unsubstituted or substituted alkyl, R.sub.3 and R.sub.4 independently of one another are each hydrogen, halo, alkyl, alkoxy or unsubstituted or substituted amino, Z is a fiber-reactive group, m and n independently of one another are each 0 or 1, provided that m.noteq.n, and l is 1 or 2. This compound is suitable for dyeing and printing cellulose fiber, natural and synthetic polyamide fibers, polyrethane fiber, leather and the like and mixed yarns thereof, to obtain dyed or printed products of a color fast to light, wetness and chlorine with superior build-up and level dyeing properties.

An asymmetric dioxazine compound of the following formula in the free acid form, ##STR1## wherein R is hydrogen, halogen, sulfo or alkoxy, R.sub.1, R.sub.2 and R.sub.3 are each hydrogen or alkyl, X.sub.1 and X.sub.2 are each hydrogen, halogen, alkyl, alkoxy or phenoxy, Y is alkylene, phenylene or naphthylene, Z is --SO.sub.2 CH.dbd.CH.sub.2, --SO.sub.2 CH.sub.2 CH.sub.2 OSO.sub.3 H or the like, V is hydrogen, alkyl, acyl or substituted triazinyl, and Q is halogen, alkoxy, amino or a group similar to that of ##STR2## provided that R is hydrogen, and Q is amino or a group similar to that of ##STR3## when V is substituted triazinyl, which is useful for dyeing or printing fiber materials to give dyed or printed products of a brilliant blue color superior in fastness properties, particularly those such as chlorine fastness with superior build-up property.

Fiber reactive asymmetric dioxazine compounds and their use as fiber

A dioxazine compound represented by the following formula (I) in the free acid form, ##STR1## wherein V is a direct linkage or ##STR2## in which R.sub.3 is hydrogen or unsubstituted or substituted alkyl, and X is a direct linkage or an aliphatic, araliphatic or aromatic bridging group, provided that X stands for the bridging group as defined hereinabove when V is ##STR3## Y is unsubstituted or substituted phenylene, or unsubstituted or substituted naphthylene, Z is --SO.sub.2 CH.dbd.CH.sub.2 or --SO.sub.2 CH.sub.2 CH.sub.2 Z.sub.1 in which Z.sub.1 is a group capable of being split by the action of an alkali, Q is sulfo, hydroxy, halo, alkoxy, unsubstituted or substituted phenoxy or unsubstituted or substituted amino, and R.sub.1 and R.sub.2 independently of one another are each hydrogen or unsubstituted or substituted alkyl, which is useful for dyeing or printing fiber materials to give a dyed or printed product of a blue color superior in fastness properties, particularly those such as chlorine fastness, with superior build-up property.
