Process for dyeing or printing hydrophobic, synthetic, organic fiber materials, characterized in that water-insoluble azo dyes of the general formula where X is an alkyl group of 1 to 4 carbon atoms or the phenyl group which may be substituted by alkyl groups of 1 to 4 carbon atoms, alkoxy groups of 1 to 4 carbon atoms, halogen atoms and / or nitro groups, and D for the rest of an aromatic Diazo component stands.n n n When using the azo dyes of the abovementioned formula, vivid and clear greenish yellow to yellowish orange colorations can be achieved on the fiber materials mentioned, such as those made from cellulose esters, polyesters, polyurethanes, polyolefins or polyamides, which are very good wet, wax, emission and lightfast are. |
