  • Transparentized paper and method for its manufacture
    Patent number: 5055354
    Abstract: Transparentized paper, free of residual solvent, is fabricated by coating a web of paper with a solvent-free transparentizing medium, allowing the medium to remain on the paper for a period of time sufficient to saturate part but not all of the thickness of the web, removing the excess transparentizing medium and storing the paper for a period of time sufficient to equilibrate the concentration of transparentizing medium in the thickness of the web. Also included are solvent-free transparentized papers produced by this method.
