| titleOfInvention | New dyestuffs of the oxazine series and process for making them |
| abstract | The invention comprises oxazine dyes of the formula: <FORM:0781384/IV (b)/1> in which R1 is a benzene residue, R2 is a benzen ring fused on to hetero ring I and containing a sulpho group, R6 is a residue of a primary or secondary amine bound to the triazine ring by its amino group and free from oxazine rings, and Y is NH2 or halogen. R6 may represent the residue of an amine of no dyestuff character, or the radical of a yellow amino-azo dye, advantageously one of the formula -NH-R3-N = N-R4 or -NH-R3-X-R5-X-R4, in which R3, R4 and R5 represent benzene residues, and one X is an azo linkages, the other being a -CONH-group. The benzene residue R4 may contain OH para to the azo- or X linkage, and COOH ortho to this OH. The dyes are made by condensing two mols. of a cyanuric halide, on the one hand, with one mol. of a diamino dioxazene of the formula: <FORM:0781384/IV (b)/2> and, on the other hand, with 2 mols. of a primary or secondary monoamine free from oxazine rings, and if desired exchanging any halogen atoms still present in the triazine residues for amino group. The products dye or print leather, silk, wool, or casein, superpolyamide or superpolyurethane fibres, regenerated cellulose, paper, linen, cotton. In examples: (1) a dioxazine sulphonic acid obtained by condensing chloranil with 4 - amino - 41 - acetylamino - diphenylamine-2-sulphonic followed by ring-closure and deacylation in sulphuric acid containing oleum (1 mol.) is condensed with 2 mols. of the product obtained by condensing equimolecular proportions of cyanuric chloride and 4 - amino - 41 - oxy - 1.11 - azobenzene - 31-carboxylic acid, or the dioxazine is condensed first with the cyanuric chloride, followed by condensation with the azo body. The azo body is replaced in another example by 4-amino-1-oxybenzene-2-carboxylic acid. Also specified as monamines are 4-amino-4-hydroxy-2-chloro-1.11 - azobenzene - 3 - carboxylic acid, 4-amino - 3 - methoxy - 31 - sulpho - 1.1 - azobenzene, 4 - p - aminobenzoylamino - 2 - sulpho-41 - hydroxy - 1.11 - azobenzene - 31 - carboxylic acid, aminobenzenes, aminonaphthalenes, aminodiphenyls, aminoaroylaminobenzenes, aminochrysene, aminopyrene, aminobenzoic acids, cyclohexylamine and aminophenylbenzthiazoles. |
