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 heterocyclic compound of the formula, ##STR1## wherein A and B are each hydrogen, alkyl or alkoxy, Y is hydrogen, alkyl, alkoxy or --O--R.sup.2 --X--R.sup.1, or Y and B are taken together with each other to form methylenedioxy, R.sup.1 is alkyl, phenyl or alkenyl, R.sup.2 is unsubstituted or substituted alkylene, and X is --O--, --S--, --SO--, --SO.sub.2 -- or ##STR2## in which R.sup.3 is hydrogen or alkyl, with the proviso that R.sup.1 is C.sub.3 or C.sub.4 alkyl or alkenyl, or C.sub.1 -C.sub.4 alkyl when R.sup.2 is unsubstituted ethylene or propylene, respectively, X is --O-- or --S--, and Y and B don't form methylenedioxy, which is useful for dyeing or printing hydrophobic fiber materials with superior dyeability to give a dyed or printed product of a red color excellent in fastness properties, particularly those such as washing fastness.

Benzodifuranone compounds useful for dyeing or printing hydrophobic

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.

Symmetrical dioxazine compounds and their use as fiber-reactive dyes

An aqueous liquid dye composition comprising a dye represented by the following formula in a free acid form, ##STR1## wherein Y is --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 X in which X is a group splittable by the action of an alkali, and a pH buffer, the dye being in the form of a lithium salt, and the liquid dye composition having a pH value of from 3 through 7 and a dye content of from 5 through 50% by weight based on the weight of the liquid dye composition, which can be stored stably for a long period of time even at a low temperature such as 0.degree. C. or lower, and a high temperature such as 40.degree. C. or higher.

C. or lower without deterioration in its solution state.

Reactive dye-containing aqueous liquid composition

A system for processing chromatographic data which comprises an input for data representative of two chromatograms x and y, a memory for storing the inputted data of the chromatograms, and a computer operative to read out, from the memory, retention times x.sub.i and y.sub.i (i=1, . . . , n; n.gtoreq.2) of at least two principal peaks of the chromatograms, respectively, and derive one function for converting the retention times x.sub.i to y.sub.i using the chromatogram y as the reference chromatogram, which gives a minimum estimated error. The computer is further operative to calculate, on the basis of the derived function, the modified retention time x'.sub.j of all the peaks of the chromatogram x. Therefore, the system permits to eliminate errors orginated from the judgment of a skilled person and to indentify and quantitatively analyze chromatogram obtained precisely without skill.
