Latest Patents
One of LaPointe's latest patents is for an image-receiving element designed for use in photographic and photothermographic diffusion transfer film units. This innovative element is intended to be removed or 'peeled-apart' from a photosensitive element after exposure and processing. The design includes a support, an image-receiving layer, and a strip-coat layer that facilitates the separation of the image-receiving element from the photosensitive element. The strip-coat layer is composed of an anion of poly(acrylic acid) or a salt thereof, complexed with a cationic quaternary salt. In a preferred embodiment, the strip coat layer may also include an ethoxylated alcohol.
Another significant patent involves polyoxyalkylene overcoats for image-receiving elements. This patent discloses diffusion transfer films and processes where the processing composition includes a light-reflecting pigment and an optical filter agent. The image-receiving layer carries an overcoat that comprises a polyoxyalkylene decolorizing agent, which is hydrogen bonded with at least one other polymer and a salt of polyvinyl hydrogen phthalate. This overcoat layer is specifically designed to decolorize the optical filter agent immediately adjacent to the interface between the processing composition and the overcoat layer.
