Abstract

Procedure for the preparation of monoazo dyes of the general formula (1) **(See formula)** in which R represents an alcohol or lower alkoxy group with 1 to 4 carbon atoms, R'represents a hydrogen atom, an alcohol or lower alkoxy group, R''represents a hydrogen atom or a lower alcohol group, Z represents an acyl radical, X represents a grouping of the formula -SO2-CH = CH2 (2) or -SO2-CH2-CH2-Y (3) in which Y means an organic or inorganic radical capable of being separated in alkaline medium or the hydroxyl group, and n means numbers 0 or 1, characterized in that an aromatic amine of formula (4) is diazotized. **(See formula)** in which R, R'and X have the aforementioned meanings, and are coupled with coupling components of the general formula (5) **(See formula)** in which R'', Z and n have the aforementioned meanings, and the dyes obtained from the aforementioned general formula (1), which by X contain the group -SO2-CH2-CH2-OH, are optionally transformed by treatment with a organic or inorganic acid or its derivatives, in the corresponding dyes with the group -SO2-CH2-CH2-Y, in which Y means an acid radical capable of being separated in an alkaline medium, or the dyes obtained from the formula are optionally transformed General (1), cited, which by X contain the group -SO2-CH = CH2, by treatment with an alkali metal thiosulfate or a dialkohilamina in the corresponding dyes with the group -SO2-CH2-CH2-SSO3-alkali metal, or -SO2-CH2-CH2-N (alcohol) 2.
