  • Patent number: 5162141
    Abstract: 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.

  • Patent number: 4709631
    Abstract: The invention is directed to a method of printing a pattern on a substrate, the liquid retained within the printing screen is in a first position directly above the point of tangency between the screen and substrate so that a lesser quantity of liquid is deposited to provide raised beads of liquid comparable in size to the size of the apertures of the screen.The reservoir of liquid is shifted away from the point of tangency and therefore a larger quantity of liquid passes through the apertures because the apertures are now spaced from the substrate. The larger quantities of liquid flow together and therefore, a pattern is provided larger than the aperture size of the screen.
