摘要： The present invention is a method of providing an imaging element which includes providing a gravure cylinder having an outer surface having a plurality cells. The surface of the cylinder is moved through a coating solution of a film forming organic polymer to fill the cells with coating solution. An imaging element is moved across the outer surface of the gravure cylinder to deposit the coating solution onto the imaging element such that a fraction of the imaging element of from 0.02 to 0.98 remains uncovered with coating solution. The coating solution is dried to form a discontinuous overcoat on the imaging element.

摘要： The present invention is an imaging element which includes a support, an imaging layer superposed on a side of said support and an overcoat overlying the imaging layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the imaging layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. The present invention is a photographic which includes a support, a silver halide emulsion layer superposed on a side of said support and an overcoat overlying the silver halide layer. The overcoat is composed of an organic polymer. The overcoat is discontinuous such that a fraction of the surface area of the silver halide emulsion layer remains uncovered by said polymer, wherein the fraction of area not covered by the said polymer is from 0.02 to 0.98. In one embodiment, the discontinuous overcoat is a series of parallel stripes.

摘要： An aqueous coating composition for forming a transparent magnetic recording layer contains a fine solid particle aqueous dispersion of dispersed magnetic particles, gelatin, and a polyelectrolyte having a molecular weight of at least 50,000. The coating composition may be prepared by milling an aqueous slurry of magnetic particles and a surface active dispersant having an HLB number of at least 8 until there are substantially no agglomerates of magnetic particles present, and then combining the milled dispersion with the gelatin and polyelectrolyte. The coating composition can be used to prepare magnetic recording elements and, in particular, photographic elements having a transparent, substantially haze-free magnetic recording layer.

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 for the preparation of electrostatographic toner including the following steps. A polymer material is dissolved in an organic solvent to form an organic phase. The organic phase is dispersed in an aqueous phase that includes a particulate stabilizer and a salt including an anion selected from chloride, oxychloride, sulfate, perchlorate, nitrate, dihydrogen phosphate, lactate, trifluoromethylsulfonate, and trifluromethylhydrate and a cation selected from aluminum, iron (III), tin (II) and zirconium (IV), to form a dispersion. The dispersion is homogenized. The organic solvent is evaporated from the dispersion and the resultant product is recovered, washed and dried. In an alternate method the salt is added directly to the dispersion.
