  • Publication number: 20120100489
    Abstract: The invention pertains to a method for rebalancing a solvent solution useful for treating photosensitive printing elements having a photopolymerizable layer. The solvent solution becomes contaminated with unpolymerized material and other materials that release from the photosensitive printing elements during washout treating, and separation of contaminates also removes some of one or more components in the used solvent solution. The method rebalances the proportion of the components in a solvent solution having 3 or more components. The method includes measuring a reclaimant, which has been separated from the contaminates, for two or more properties, calculating a mass of the components to be added to the reclaimant based on an equation generated for each measured property, and adding the mass of the component or components to the reclaimant to adjust the proportion of the components in the reclaimant to targeted proportions.

  • Patent number: 6319658
    Abstract: The present invention is also directed to a method of photoprocessing a photographic imaging element having a processing-solution-permeable overcoat that comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble hydrophilic polymer. During photoprocessing, a surface-active water-soluble hydrophilic polymer is leached into a photoprocessing solution. However, foaming due to the hydrophilic polymer in the photoprocessing solution is prevented by the presence of a non-ionic surfactant having an HLB of less than 12.

  • Publication number: 20010026910
    Abstract: A multi-part color developing kit includes at least two parts (or solutions) of photochemical compositions that can be mixed to provide a color developing composition useful for obtaining color photographic images. A first aqueous solution is formulated with a color developing agent in free base form, an antioxidant for the color developing agent, an inorganic base, a triazinylstilbene optical brightening agent, an chemical base and a water-miscible or water-soluble hydroxy-substituted, straight-chain organic solvent. A second aqueous solution is formulated with a buffering agent, the same or different chemical base and a phosphonic acid metal ion sequestering agent. Both solutions have a pH and homogeneity to provide a clear color developing composition that is safer for use and disposal.

  • Patent number: 6284440
    Abstract: The present invention provides a method for formation of a pattern of a photosensitive resin composition, which method is superior in sensitivity and film-thinning ratio, generates no scum in pattern formation, and gives a high resolution. That is, the present invention lies in a method for forming a pattern of a photosensitive resin composition, which comprises coating, on a substrate or the like, a positive photosensitive resin composition composed of a polyamide of particular structure and a diazoquinone compound, subjecting the resulting material to prebaking and then to light exposure, and dissolving and removing the exposed portions of the material with an aqueous alkaline solution containing an anionic surfactant and at least one kind of compound selected from compounds of calcium, strontium and barium, to obtain a pattern. The feature of the present invention lies particularly in using such an aqueous alkaline solution as a developing solution.

  • Patent number: 6280912
    Abstract: The present invention provides an overcoat for a photographic element that allows for appropriate diffusion of photographic processing solutions. The overcoat comprises 10 to 50% by weight of a enzyme-degradable biopolymer and 50 to 90% by weight of hydrophobic particles (by weight of dry laydown of the entire overcoat). An enzyme is applied to the element before, during, or after conventional photoprocessing. According to one embodiment of the invention, the photographic element can be exposed and processed using normal photofinishing equipment, with no modifications, to provide an imaged element together with a protective, water-resistant layer.

  • Patent number: 6258520
    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: 6187519
    Abstract: A tetraalkylammonium hydroxide (TAAH) solution recovered from a development waste through separation therefrom of impurities such as photoresist is mixed with a surface-active substance to have the surface tension thereof adjusted to a desired one, and then reused as a rejuvenated developer. Thus, the surface-active effect (wetting properties) of the rejuvenated developer recovered from the development waste is properly adjusted and controlled, whereby fine photoresist patterns can be stably and effectively developed. Usable surface-active substances include surfactants, and dissolved photoresist contained in the development waste or a photoresist-containing solution such as a photoresist-containing treated solution derived therefrom.
