  • Publication number: 20090047449
    Abstract: Processes are disclosed for preparing a printable and printed articles by coating a substrate with a composition containing a crosslinkable amine functional polymer and a polyfunctional isocyanate blocked by a blocking agent. The coated substrate is heated to a sufficient temperature to deblock the blocked polyfunctional isocyanate and thereby produce a crosslinked hydrophobic, ink receptive polymer layer on the substrate. Printed articles are prepared by forming an image on the crosslinked hydrophobic, ink receptive layer. In a preferred embodiment, the crosslinked hydrophobic, ink receptive polymer composition is characterized by a solvent resistance fraction of at least 0.6 and a solvent absorbance capacity of at least 300. The substrate of the printed article is preferably polymer, metal, glass, or paper, more preferably polymer film. A process for preparing printable articles wherein the substrate is a fluoropolymer is especially preferred.

  • Patent number: 7070675
    Abstract: Fluoropolymer films which combine the attributes of outdoor durability, chemical resistance and thermoformability with paint-like aesthetics are formed into film structures which have at least one surface coated with a primer of amine functional polymer and an overcoat of a thermoplastic adhesive of acid modified polyolefin. Fluoropolymer films so coated are securely bonded to a variety of thermoplastic substrates forming a laminated film structure which resists delamination when exposed to moisture and humidity.
