Process for the preparation of fluorescent 4- (4,5-arylene-1,2,3-triazolyl-2 -) - cyanothilbene compounds, soluble in organic solvents, particularly applicable for the rinsing of hydrophobic organic material, characterized in that it is diazotized a 4-aminocyanthylbenzene compound having the cyano group in the amino-containing benzene ring of the stilbene radical, is ortho position with respect to the vinyl bridge, or at any position of a benzene ring free of amino groups of the stilbene radical, the diazo compound is copulated with an azocomponent that copulates neighboring a primary amino group, oxidizing the O-aminoazoic dye obtained in 1,2,3-triazole compound, to which effect the components are selected in such a way that the final product does not contain neither acid substituents that form salts, nor substituents that produce color.
