Process for the preparation of metallizable monocazo dyes and their heavy metal complex compounds, characterized in that a benzethiazonium compound containing ortho with respect to the diazo group is coupled to a hydroxyl group, or a substituent group transformable into a hydroxyl group, and which can be even further substituted, with a 4-methyl-1-oxybenzene compound such that it still contains in positions 2 and 5 a methyl group and an acylamino group, after which the obtained dye is transformed, in substance or on the fiber, possibly under transformation of ortho substituents with respect to the azo group in the hydroxyl group, in complex chromium or cobalt compounds.
