Abstract

Procedure for dyeing or printing organic materials with developmental azo dyes, in which diazo salts and coupling components are brought onto the organic material to be dyed or stamped successively or simultaneously and are coupled together, characterized in that as components For coupling the diazo components, in the dye-forming reaction in the same organic material to be stained, at least one of the following formulas is selected: **(See formula)** in which R1 means hydrogen, an optionally substituted alkyl group, a fibroreactive acylaminoalkyl group, an optionally substituted aryl radical, a heterocyclic radical, an alkylene radical, which links the radical of the formula (1) with another heterocyclic radical of the same class, an optionally N-monosubstituted or N-disubstituted amino group, R2 means hydrogen, an optionally substituted alkyl group, cycloalkyl, cyano, nitro, nitroso, H2N, an acylamino group that eventually shows monoreactive groups, an alkylcarbonyl, arylcarbonyl or sulfonyl group, an aminosulfonyl group, an alkoxycarbonyl radical or aryloxycarbonyl, an aminocarbonyl group, a halogen atom, a sulfoalkyl group, an acylaminomethyl group, in which the acyl radical corresponds to the formula -CO-RX, where R is an alkyl ene group and X a halogen atom, a quaternized amino group or a sulfo group, or a group of the formulas **(See formula)** in which the two groups -C0- or -SO2- are linked in a neighboring position to a 6-membered aromatic ring, the sulfo or carboxyl group, a quaternized amino group or a group of the formula **(See formula)** in which the hydrogen atom is part of a 5- or 6-membered ring, which may still contain other heteroatoms, such as nitrogen or oxygen atoms, R3 signifies hydrogen, an optionally substituted alkyl group, an optionally substituted aryl radical, a heterocyclic radical, the cyano group, an alkoxycarbonyl or aryloxycarbonyl radical, an aminocarbonyl group, an alkoxycarbonylmethyl or aryloxycarbonylmethyl radical, a cyanomethyl group, a group of acylomethyl, an aminocarbonyl group, the carboxyl group or the hydroxymethyl group, or those of formula (2) **(See formula)** in which R2 and R3 have the meanings indicated in the explanation of formula (1) and X means a group - (CH2), where n is 2 or 3 or a radical of the formula **(See formula)** and of the formula (3) **(See formula)** in which R1 has the significance indicated in the explanation of formula (I), and R2 and R3 together with the carbon atoms of the pyridone ring, to which they are attached, form a 5- or 6-membered ring, for example composed of the formulas **(See formula)** in which R1 has the significance indicated in the explanation of formula (I), and H indicates on the ring the fully hydrogenated state of the respective ring, as well as those of formula (4) **(See formula)** in which X means the hydroxyl or amino group e Y means a hydrogen or halogen atom.
