摘要： The present invention is a photographic element which includes, in order, a transparent support, at least one silver halide emulsion layer superposed on the support, optionally a white or diffuse reflective layer, and a processing-solution-permeable protective layer on the backside, which protective layer becomes water-resistant in the final product without lamination or fusing. The present invention is also directed to a method of making a photographic print involving developing the photographic element. 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.

摘要： 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.

摘要： The present invention relates to the use of fine metal particles for the recovery of silver from a silver-bearing photographic waste solution. In particular, the metal particles are encapsulated in a hydrophilic colloid that allows for the permeability of water and silver ions. When contacted with the silver-bearing photographic waste solution, the hydrophilic colloid will imbibe water and swell. At the same time, the silver ions can permeate the colloid matrix and come into contact with the metal particles, preferably iron particles, at which point a metal—metal exchange reaction takes place.

摘要： A method of processing a photographic imaging element to obtain a protective overcoat is disclosed, which overcoat provides, in the final product, resistance to fingerprints, common stains, and spills. More particularly, the present invention involves a processing-solution-permeable overcoat that becomes water and stain resistant in the photochemically processed product. The overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer. During development or thereafter, before drying, the water-soluble polymer is removed to a significant extent. Subsequently, the imaged element is dried at an elevated temperature to facilitate coalescence of the overcoat to thereby provide enhanced stain resistance and water-resistance.

摘要： Disclosed herein are hydrophobically-modified poly(aminoamides) useful as fixative detackifiers for stickies and pitch control in papermaking processes. These polymers are prepared via modification of amine-containing water-soluble poly(aminoamides) with reactive functional group-containing hydrophobic compounds. In particular, poly(aminoamides) may be modified, under appropriate reaction conditions, with long chain alkyl glycidyl ether, AKD (alkyl ketene dimer), ASA (alkyl succinyl anhydride), or Quab (3-chloro-2-hydroxypropyl-N,N,N-dimethylalkyl ammonium chloride). These novel polymers are effective in inhibiting deposition of organic contaminants in pulp and papermaking systems.

摘要： The present invention is a method of manufacturing polymer particles. The method includes providing an oil in water emulsion, wherein the oil phase comprises a volatile solvent and at least one water insoluble polymer. The volatile solvent has a solubility of not more than 10% in water and the water insoluble polymer has a weight average molecular weight of at least 2000. The water insoluble polymer is soluble in the volatile solvent. The emulsion is supplied to a rotating surface of a rotating surface reactor. The temperature of the rotating surface is maintained at the boiling point of said solvent or greater. The rotating surface of the reactor spins at a speed sufficient to cause the emulsion to spread over the rotating surface as a continuously flowing thin film wherein a vapor phase containing the volatile solvent is removed. The water insoluble polymer particles are then collected as a slurry of polymer particles and water.

摘要： An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt % and gelatin hardener at a level from 1-200 effective &mgr;mole hardener per gram of coating fluid, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. Relative improvements are obtained in reducing the rate of chemical gelation of a coating fluid containing gelatin and a hardener, without the need for chemically modifying functional groups of the gelatin. The invention further enables an increase in coating fluid concentration, increase in the fluid viscosity, reduction in the ratio of added anionic polymer to gelatin, and/or increase in the pH of a coating fluid containing gelatin and a hardener, without detrimentally increasing the rate of chemical gelation of the coating fluid. The invention also enables the inclusion of relatively more reactive hardeners in a coating fluid containing gelatin, and/or the inclusion of relatively higher molecular weight gelatin in a coating fluid containing hardener, without detrimentally increasing the rate of chemical gelation of the coating fluid. Each such advantage may be achieved either individually, or in combinations to varying extents.
