    摘要: The adhesive system of the present invention is suitable for use in adhering an incompatible ink system to a polymeric film; particularly, adhering a lithographic ink or electrographic toner bonded to a floor covering. The polymeric sheet and incompatible ink have a primer layer interposed between them or the ink layer is encapsulated between the two primer layers. The primer may be solvent based or aqueous based and preferably includes a benzene derivative, ketone, acetate or nitroparaffin solvent or film former. The primer is compatible with the polymeric sheet and diffuses into the ink layer. The preferred solvent or film former includes methyl isobutyl ketone, methyl ethyl ketone, n-propyl acetate, isopropyl acetate, or N-methyl-2-pyrrolidone. The primer also includes a polyvinyl resin, acrylic resin, polyurethane resin or polyester resin, and optionally a pigment. To deter dot distortion of the ink, the primer should have a glass transition temperature (T.sub.g) of at least about 60.degree. C., and preferably at least about 100.degree. C.

    摘要: Thermal insulation is prepared using gelatin foam. Embodiments of gelatin foam insulation which are described include gelatin foam having an anti-wicking agent which is an aromatic compound having as ring substituents: an --NH.sub.2 moiety and/or a hydroxyl moiety and also at least two sulfonate moieties. In another embodiment, the gelatin foam is combined with phyllosilicate mineral lamellae for void control and as a shrinkage deterrent. In yet another embodiment, crosslinked gelatin foam is described which has been crosslinked with a melamine/formaldehyde condensation product, a polyfunctional aziridine and/or an epichlorohydrin/polyamide condensation product.
