Abstract
An erasable imaging medium comprises a photochromic aziridine of specified formula coated on a substrate, the aziridine being mixed or coated with a transparent oxygen- impermeable substance which preferably inhibits crystal growth e.g. polyvinylalcohol or gelatin. The aziridines are imaged using an electron beam or U.V. light and bleached with visible radiation. Dyes may be incorporated in the transparent substance to give sensitivity to different wavebands and the substance may be covered with a water-proof plastics layer. The aziridines may be deposited by sublimation onto a cold substrate, below -120 DEG C, or from a benzene solution to give a homogeneous or monocrystalline layer. The medium may be used to measure dosage of U.V. light e.g. by sunbathers or in the treatment of psoriasis by comparison of the changed colour with a calibrated standard, or to measure daylight as the coloured medium bleaches.
