Abstract

In the course of slow evaporation of an azo-dye chrysophenine-saturated gelatin-water solution, dye crystals that developed two different interference colors were observed in the gelatin; the colors were yellow and blue. The crystals that produce a blue interference color undergo disintegration on exposure to non-polarized light from a mercury lamp.
