Abstract

A method of producing a fleeting dye comprising subjecting an aqueous solution of a polyethyleneoxy aromatic compound to an excess of nitrous acid at a ph comprised between about 2 and 5 to directly form a diazonium salt and reacting the diazonium salt with a nucleophilic compound for copying the salt therewith and forming a fleeting dye.
