ABSTRACT:
Work clothing, having an optical warning effect, which has been dyed in specific, prescribed color shades and is not coated with plastics is desired by the authorities. Thioindigo and/or derivatives of the red and pink series of thioindigo, as the base dyestuff, in combination with specific yellow disperse dyestuffs have proved usable, for dyeings on polyester fibers or polyester/cotton fiber mixtures, which are in the required shade of fluorescent orange-red and meet the requirements regarding color point, luminance and fastness to light. Both the exhaustion process and the thermosol process can be used to produce these dyeings.
