  • Storage-stable photoimageable deutero leuco dye/photooxidation compositions with improved leuco dye
    Patent number: 5744280
    Abstract: Storage-stable photoimageable leuco dye/photooxidant compositions and imaging processes utilizing these compositions are disclosed. These compositions comprise deuterated leuco compounds, e.g., deuterated aminotriarylmethanes, wherein the extent of deuteration is preferably at least 60%. These new compositions and the processes utilizing these new compositions afford improved monochrome images having enhanced film stabilities and image contrast characteristics, wherein desirable higher optical densities in imaged areas (D.sub.imaged) and desirable lower optical densities in unimaged areas (D.sub.unimaged, D.sub.fixed, and D.sub.forccd) are simultaneously both achieved in accordance with the compositions and processes of the instant invention.

  • Process of making colored images using aqueous processable photosensitive elements
    Patent number: 5093221
    Abstract: A photosensitive element adapted for the preparation of colored images is disclosed. The photosensitive element comprises: a photosolubilizable layer consisting essentially of an acid-labile polymer and a photosolubilizing agent; an elastomeric layer; and a support. It can be processed by aqueous solvents, preferably ordinary tap water.
