Abstract

Oil is encapsulated in polymeric envelopes by known methods; the resulting microcapsules are uniformly distributed in a paper pulp; paper sheets or strips are produced in the normal way and then subjected to pressure to crush the microcapsules. By this method, the oil is uniformly distributed throughout the paper and staining during the production is avoided. Semi-transparent papers so produced are suitable for photographic applications, as the paper, being less hydrophobic than known oil-impregnated papers, has a good receptivity for photographic emulsions. These papers have also good ink-receptivity and resistance to oils (parchment). Suitable oils include tributyl and tricresyl phosphates, paraffin, ethyl and butyl phthalates, butyl oleate, amyl laurate, diphenyl derivatives and natural fatty oils. Suitable polymeric materials include gelatin, casein, sodium alginate, gum arabic, styrene-maleic anhydride copolymers, urea-formaldehyde resins, polyisocyanates, polyamines, epoxy resins, waxes, polystyrene, polyvinyl chloride and vinyl chloride-vinyl acetate copolymers. The microcapsules are preferably used in an amount of 20% with respect to the weight of dry paper substance.
