Abstract: A medium which is hydrophobic when unexposed, and hydrophilic when photon exposed is employed to produce discrete photondeveloped areas. The medium comprises a solid dispersion in a film-forming binder of a photoconductive sensitive material such as zinc oxide, a sensitization enhancing material such as a copper salt and a hydrophobicity inducing agent such as a water repellent silicone, fluorocarbon material or a higher molecular weight organic acid such as stearic acid or linoleic acid. Exemplary processes of developing the photon exposed medium include application of aqueous liquids to form visible and/or transferable or relief images.
