摘要： PAPERS CONTAINING EXPANDED THERMOPLASTIC MICROSPHERES ARE PREPARED BY INCORPORATING AN EXPANDABLE THERMOPLASTIC MICROSPHERE WITHIN THE PULP SLURRY AND THE PAPER DRIED AT ABOUT 90*C., CAUSING THE MICROSPHERES TO FOAM. THIS PHENOMENON APPEARS TO BE PECULIAR TO MICROSPHERES HAVING A VINYLIDENE CHLORIDE-ACRYLONITRILE COPOLYMER SHELL.

摘要： A fibrous sheet having a high strength and water resistance and having no resin specks on the surface can be produced by producing a sheet from a fiber slury by the known paper making process, to said fiber slurry being added a flocculate of chlorinated polymer latices which has a particle size of 100.mu.-500 .mu. and is prepared by heating said chlorinated polymer latices to a temperature of at least their minimum film-forming temperature and then adding a water soluble cationic polymer or a polyvalent metal salt with stirring. Examples of said chlorinated polymer latices are anionic polyvinyl chloride latex, polyvinylidene chloride latex or the combination thereof.

摘要： The electrostatic recording material comprises an electroconductive transparentized base sheet having a dielectric layer thereon. The transparentized base sheet is obtained by subjecting to a transparentizing treatment with moisture, heat and pressure a fibrous matrix sheet of a mixture of natural pulp with synthetic pulp formed of a blended polymer system consisting essentially of polyvinyl alcohol-acrylonitrile copolymer and acrylonitrile-styrene copolymer.
