Abstract
Process for the preparation of asymmetric compounds of bis-4,5-arylene-1,2,3-triazolyl-ethylbenzene, particularly applicable for the optical rinsing of organic and textile materials, and for the preparation of means for optical rinsing of such materials, optionally in combination with means for washing or other treatment thereof, characterized in that the amino groups are diazotized in a stilbene compound containing two diazotizable amino groups, or a diazotizable amino group and a 4,5-arylene-1 group, 2,3-triazolyl- (9, and one of these two substituents in position 4 and the other in a position other than the 4th position, the diazo compound is coupled with an azocomponent which copulates in a position close to a primary amino group or in position adjacent to a substituent that can be transformed into such a group, optionally transforming it into the O-aminoazoic dye and oxidizing it according to known methods, into the bis-4,5-arylene-1,2 compound, 3-triazolyl- (2) -stilbene, selecting the components for this purpose so that the bis-4,5-arylene-1,2,3-triazolyl-stilbene compound does not contain any color-producing substituents.
