Abstract: The influence of the main components of diazo film, such as couplers, diazonium compounds and binders, on the color of the dye image was studied.The results showed that the color of the dye image is strongly dependent on the structure of the coupler and the substituents on the aromatic nuclei of the diazonium compound.It was demonstrated that the binder also has certain effect on the color of the dye image.
