  • Method and apparatus for thermal development with vapor treatment
    Patent number: 7491003
    Abstract: This invention pertains to a method and apparatus for thermally developing a photosensitive element. The photosensitive element includes a composition layer capable of being partially liquefied upon heating. Heating the layer causes one or more organic compounds in the layer to form a vapor. Oxidation of the vapor forms carbon dioxide and water vapor and reduces the need to manage waste streams containing the organic compounds.
