Abstract

There is described a reversible imaging and recording member which comprises a layer of 1-isopropylanthracene (1-IPA) molecularly dispersed in a polymeric binder residing on a layer of a charge carrier generating material such as, for example, selenium. The 1-IPA has extraordinarily high solu-bility in many solid polymer matrices and the reversible di-merization of the 1-IPA is accompanied by changes in the physical properties of 1-IPA-binder system such as refractive index, specific volume, photoconductivity, surface energy, etc. A latent image can be formed on the member by imagewise irradiation with ultraviolet light near 360 nm which is accom-panied by dimerization in the exposed areas. The member is then corona charged, illuminated with weak diffuse light and contacted with toner material to form a visible image. The member may also be utilized for reversible holographic re-cording and relief imaging.
