Abstract Mixtures of cholesteryl iodide and cholesteryl bromide with cholesteryl nonanoafce were exposed to UV radiation and the resultant color shifts were measured as a function of exposure and composition. The formation of images by this process will be described, and the presiding mechanism will be briefly discussed.
