Publication number: 20040242758Abstract: This invention relates to ink-receptive coating compositions and to articles containing a layer formed from such coating compositions. In one embodiment, the articles comprise a polymer film substrate and an ink-receptive layer on the upper surface of the polymer film substrate. In another embodiment, the article also comprises an adhesive layer on the bottom surface of the polymer film substrate. The articles may have a print image on the upper surface of the ink-receptive layer, and such print images exhibit improved performance when exposed to extreme environments such as high temperatures, water, solvents and abrasion.Type: ApplicationFiled: November 7, 2003Publication date: December 2, 2004Inventors: Frank Yen-Jer Shih, Walter J.

Patent number: 6824602Abstract: An improved block paving sand comprising kiln dried sand mixed with a water-soluble polymer. The block paving sand is filled into gaps between blocks and then water is applied thereto. Upon contact with the water, the polymer coats the sand and then sets hard, thereby stabilising the block paving.Type: GrantFiled: August 30, 2002Date of Patent: November 30, 2004Inventors: Paul Andrew Darby, John Thomas Liddy

Patent number: 6815483Abstract: Copolymers of polycarbonates or polyarylates with polyether polymers such as polyethersulfones, polyetherketones, and polyetherimides are prepared by reaction of the polyether polymer-forming reagents, e.g., bisphenol A disodium salt and bis(4-chlorophenyl) sulfone, in the presence of the polycarbonate or polyarylate. The reaction may take place in a dipolar aprotic solvent, or in a water-immiscible aromatic solvent in the presence of a phase transfer catalyst, preferably a hexaalkylguanidinium halide. Hydroxy-terminated polyether oligomers may be produced from the copolymers by saponification of carbonate or ester groups.Type: GrantFiled: December 10, 2001Date of Patent: November 9, 2004Assignee: General Electric CompanyInventor: Tohru Takekoshi
