摘要： An imaging element is described comprising one or more hydrophilic colloid layers which include gelatin as a film forming binder which has been chemically crosslinked with a gelatin hardener, wherein at least 20% of the gelatin of at least one of the one or more hydrophilic colloid layers comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide, and the gelatin is chemical crosslinked with a gelatin hardener at a level from 70 to 120 effective &mgr;mole hardener per gram of gelatin. Improvements are obtained in the wet mechanical strength of an imaging element comprising gelatin as a binder, without needing to increase the amount of chemical crosslinker with respect to the gelatin. The invention further enables the use of relatively low molecular weight gelatins without compromising the wet mechanical strength of imaging elements and without needing to increase the amount of crosslinker relative to the amount of gelatin. The invention also enables the selective improvement in the wet mechanical properties of layers with a high ratio of non-binder materials to binder without substantially increasing the amount of chemical crosslinker.

摘要： An aqueous coating fluid is described comprising gelatin at a concentration of at least 1 wt % and a colloidal particle dispersed material phase at a volume fraction of at least 0.01, wherein at least 20% of the gelatin comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide. The present invention enables increasing the concentrations of a coating fluid containing gelatin and dispersed sub-micron colloidal materials, reducing the size of the sub-micron colloidal materials in such a coating fluid, and/or including higher molecular weight gelatin in such a coating fluid without detrimentally increasing the viscosity of such fluids. The invention further enables reducing the viscosity of an aqueous coating fluid containing gelatin and dispersed insoluble colloidal material, without needing to reduce the concentration of gelatin or colloidal materials, increase the size of the sub-micron colloidal materials, and/or reduce the molecular weight of the gelatin. Each such advantage may be achieved either individually, or in combinations to varying extents, without the need to fundamentally change the composition of the materials in the coating fluid.

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： 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.
