The resulting print is viewed through the support, which provides protection against scratches and stains, while the polymeric overcoat provides water and stain protection to the reverse of the print where minor scratches or damage are not critical, since the image is not viewed from this side. Thus, this invention provides for a tough, stain resistant and transparent viewing surface and a stain resistant back side, which is permeable to processing solutions.

  • Patent number: 6455240
    Abstract: A method of reducing the tendency toward formation of coating non-uniformities in the coating of multilayer photographic elements is disclosed. More particularly, the present invention involves the coating of a non-gelatin coating over a topmost gelatin layer in a photographic element. In one embodiment, a processing-solution-permeable overcoat is simultaneously coated with the emulsion layers onto a photographic substrate, which overcoat becomes water and stain resistant in the photochemically processed product. In the latter embodiment, the overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer.

  • Patent number: 6342338
    Abstract: A black-and-white silver halide photographic film material, particularly suitable for use in radiography, has been disclosed, said material comprising a transparent film support having first and second major surfaces coated with a subbing layer, further coated adjacent thereto on one side (for a single-side coated material) or on both sides (for a duplitized material) of said film support and overcoated with a protective antistress layer, a light-sensitive silver halide emulsion layer having chemically and spectrally sensitized {111} tabular hexagonal grains, accounting for at least 50% of the total projective surface of all grains, wherein said film material is coated with a low amount of silver and wherein said protective antistress layer(s)and/or another hydrophilic non-light-sensitive layer comprise(s) a compound according to general formula (I) in an amount of at least 0.5 mmole per mole of coated silver halide, as claimed.

  • Patent number: 6326131
    Abstract: An imaging element is disclosed comprising a support, an imaging layer, and an outermost protective layer on at least one side of the support which comprises a lubricant and an additive which is immiscible with and more surface active than the lubricant, wherein the lubricant is present in an amount of at least 5 mg/m2 and the additive is present in an amount of at least 25 wt percent relative to that of the lubricant, the amount of additive being effective to increase the coefficient of friction for the outermost layer after coating and drying thereof relative to that obtained in the absence of the additive material. Imaging elements comprising highly lubricated protective outermost layers in accordance with the invention advantageously provide increased scratch and wear resistance, while the presence of an additive which is immiscible with and more surface active than the lubricant surprisingly has been found to increase the coefficient of friction to provide good manufacturability of the imaging element.

  • Patent number: 6190843
    Abstract: The present invention relates to imaging elements, including photographic elements and recording media, having a protective overcoat that resists fingerprints, common stains, and spills. More particularly, the present invention provides a processing-solution-permeable protective overcoat that is water resistant in the final processed product. The overcoat, before formation of the image, comprises hydrophobic polymeric particles in a gelatin matrix. Subsequent treatment of the overcoat, after formation of the image, to remove the gelatin, causes coalescence of the hydrophobic particles, resulting in the formation of a water-resistant continuous protective overcoat.

  • Patent number: 6187517
    Abstract: The present invention provides a gelatin-based aqueous-coatable overcoat for a photographic element that allows for appropriate diffusion of photographic processing solutions. The overcoat comprises 10 to 50% by weight gelatin and 50 to 90% by weight of hydrophobic particles (by weight of dry laydown of the entire overcoat) having an average diameter of 10 to 500 nm. A proteolytic enzyme is applied to the clement in reactive association with the overcoat layer. A photographic element according to one embodiment of the invention can be exposed and processed using normal photofinishing equipment, with no modifications, to provide an imaged element together with a protective, water-resistant layer.
