Abstract

Procedure for the preparation of water soluble monoazo dyes of the general formula (1) ** (See formula) ** where X means the group -CH = CH2 or -CH2-CH2-Z, where Z represents a hydroxyl group or an organic or inorganic radical capable of being separated in alkaline medium, and where A represents the radical of a component of coupling of the series of benzene, naphthalene, acetoacetic acid arylamides, or pyrazole, which contains at least one aqueous-solubilizing group, characterized in that naphthylamines of the general formula (2) are diazotized ** (See formula) ** where X has the aforementioned meanings, and are coupled with coupling components of the general formula (3) H-A (3) wherein A has the aforementioned meanings, and the dyes thus obtained of formula (1), optionally, a) in the case where X represents the grouping of the formula -CH2-CH2-OH, are transformed according to procedures per se known in dyes of the formula (1), in which X represents the group of the formula -CH2-CH2-Z, where Z means an organic or inorganic radical capable of being separated; or b) in the case where X represents the grouping of the formula -CH2-CH2-Z, where Z means a hydroxyl group or an organic or inorganic radical capable of being separated, they are transformed according to procedures known per se in dyes of formula (1), in which X represents the vinyl radical; or (c) in the case where X represents the vinyl radical, they are transformed according to per se known procedures into dyes of formula (1), in which X represents the group beta-thiosulfate-ethyl or beta-dialkoxylamino -ethyl.
