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： 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.

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.

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 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.
