Abstract: A liquid fluoropolymer coating composition and a process for using the composition to make fluoropolymer coated polymeric substrates. The liquid fluoropolymer composition comprises fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride polymer, solvent, and compatible adhesive polymer comprising functional groups selected from carboxylic acid, sulfonic acid, aziridine, amine, isocyanate, melamine, epoxy, hydroxy, anhydride and mixtures thereof. In the process, the composition is applied to a polymeric substrate comprising functional groups on its surface that interact with said compatible adhesive polymer to promote bonding of said fluoropolymer coating to said substrate. The solvent is removed from the coating composition applied to the substrate to form a fluoropolymer coating on the substrate.

Abstract: This invention provides printed and print receptive articles and processes for making such articles. The articles have a substrate coated with hydrophobic, ink receptive polymer composition characterized by a solvent resistant fraction of at least about 0.6 and a solvent absorbance capacity of at least about 300%.

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.

Abstract: The present invention is directed to a tipping paper adapted for wrapping a filter of a smoking article. The tipping paper contains a pigment made from calcium carbonate particles having a median size of between about 0.1 microns to about 0.5 microns. The calcium carbonate pigment can be used to create a tipping paper having an opacity of up to at least 89%. In comparison to conventional tipping papers, it has been surprisingly discovered that the tipping paper of the present invention reduces knife wear of a cutting instrument used to cut the paper and is less retentive to solvents when the paper is printed with a solvent based ink or covered with a solvent based coating.
