ABSTRACT:
Process for dyeing or printing synthetic or artificial hydrophobic textile fibers in an aqueous medium with a 1:1 premetallized dyestuff complex of monocationic character of a transition metal, the cationic part of which dyestuff does not contain an ionized group (dyestuff (I)), in which the fibers are treated at a temperature at least equal to 80.degree. C. with a complexing agent (III), sparingly soluble in water and not containing an ionized group and more soluble in the fiber than in the aqueous dyeing medium of pH from 3 to 7, and with the premetallized dyestuff (I), the complexing agent being capable of fixation on the metal of the premetallized dyestuff with liberation of a proton, and synthetic or artificial hydrophobic textile fibers dyed or printed by such process.
