Abstract: Provided is a process for making a paper based product which comprises first preparing a slurry of a cellulosic pulp, a particulate binder substantially insoluble in water, and an emulsion comprised of lecithin and a fatty acid or derivative thereof. This slurry is then drained of liquid to form a web, with the web being dried to provide the paper based product. The preferred polymeric binder is a hydrolyzed polyvinyl alcohol powder, which binder can be present in the final dried product in amounts of up to about 20 weight percent or more. The use of the emulsion comprised of lecithin and a fatty acid or derivative thereof permits a web containing such a high amount of sticky polymeric binder to be dried at high temperatures, without the web sticking to the drying cans generally used in commercial processes. The process of the present invention thereby permits one to efficiently prepare such a paper based product using conventional, commercial papermaking machinery.

Abstract: Provided is a high tear strength, high tensile strength paper product. The product comprises a wood pulp fiber, a non-cellulosic synthetic fiber having a tear strength enhancing denier and length, and a binder material. The resulting paper product exhibits a combination of tear strength and tensile strength which can equal that of cotton cloth of the same basis weight, and can therefore be used as a less expensive substitute for cotton cloth in many applications.

Abstract: Provided is a conductive coating composition which comprises a colloidal dispersion of cuprous iodide particles in a binder resin solution which contains an ohmic bridging electrolyte. The preferred ohmic bridging electrolyte is potassium iodide. The colloidal dispersion also preferably exists in an aqueous system, with the binder resin being a water soluble polymer such as a polyvinyl alcohol. Upon coating a support with the dispersion, a transparent conductive coating is achieved comprised of ohmic bridged cuprous iodide particles and the binder resin. Such a coating composition can be advantageously used in the manufacture of imaging elements, and provides many advantages in the handling and manufacture of the imaging elements, as well as in the adhesive properties exhibited by the imaging elements.
