  • Patent number: 8546070
    Abstract: A color photographic element has a reflective support and a blue light sensitive color record, a green light sensitive color record, and a red light sensitive color record can be used to provide color photographic prints. The element also has a non-light sensitive interlayer between the green light and red light sensitive color records. This interlayer comprises a hydrophilic colloid and an acrylic latex polymer having a glass transition temperature (Tg) of less than 0° C. The presence of this acrylic latex polymer in the interlayer reduces the formation of a cyan line defect when the color photographic print is folded or creased, such as in photobooks.

  • Patent number: 6787295
    Abstract: There is disclosed a method of preparing a photographic solid fine-grain dispersion, the method comprising the steps of: successively bringing a slurry of a water-insoluble photographically useful compound in a grinding chamber of a dispersing machine, which chamber is filled with media, allowing the compound to contact the media in the grinding chamber, to produce fine grains of the compound successively, successively separating the media from the compound by centrifugal force, and taking the compound out of the grinding chamber, using specific media with given physical properties. There is also disclosed a dispersion obtained by the method. According to the method, the photographic solid fine-grain dispersion is prepared efficiently, without coarse grains or abrasion materials resulting from media or so, and the dispersion causes no defect when coated in a form of a coating film.

  • Patent number: 6750002
    Abstract: A process for preparing a concentrated photographic spectral sensitizing dye-water composition which comprises adding an anionic sensitizing dye to an aqueous medium in the substantial absence of organic solvent, and agitating the combined dye and aqueous medium, wherein the anionic dye forms a liquid-crystalline dye phase in the aqueous medium and the agitation is performed in the presence of a nonionic surfactant having an HLB of less than 12 and an aqueous solubility at 25° C. of greater than 10 ppm, which nonionic surfactant is in the aqueous medium at a level of from 10 to 1000 ppm. In a specific embodiment of the invention, where the viscosity (at 0.1 s−1 shear rate) of the dye-water composition in the absence of the nonionic surfactant would be greater than 100 cp and especially where such viscosity would be greater than 500 cp, the surfactant is preferably present at a level sufficient to substantially reduce air entrainment during agitation of the dye-water composition.
