Patent number: 6136439Abstract: A monolayer printable polymeric film and method for making the film. The film is formed by mixing a structural material, such as polypropylene or polyethylene, with a printable material, such as vinyl-acetate or methacrylate, to form a unitary mixture prior to processing.

The receptor layer has a coated amount in a range of 6 g/m.sup.2 or more and 22 g/m.sup.2 or less, or alternately has a substantial thickness in a range of 7 .mu.m or more, which is defined by excluding a portion of the receptor layer infiltrating the substrate. A surface of the substrate may has physical properties in which a surface texture is in a range of 471 or less in terms of a roughness index, and a surface roughness is in a range of less than 2.1 .mu.m in terms of an arithmetical mean deviation of profile(Ra), less than 23.2 .mu.m in terms of a maximum height (Rmax) and less than 20.8 .mu.Type: GrantFiled: July 10, 1998Date of Patent: October 10, 2000Assignee: Dai Nippon Printing Co., Ltd.Inventors: Satoshi Narita, Takayuki Imai

Patent number: 6117509Abstract: A label sheet which is formed by stacking an adhesive layer, an inorganic reinforcement layer, a polyester film layer and a bar-code print layer on a releasable substrate layer in sequence is provided. According to the present invention, a glass frit is added to the adhesive layer of the label sheet, and not to the bar-code print layer, so that problems caused from the glass frit in the bar-code print layer can be eliminated and the adhesive layer itself can fix the shape of the label sheet. In addition, thermal stability at high temperatures is improved by the characteristics of individual layers constituting the label sheet, so that the bar-code is not damaged by a thermal process.Type: GrantFiled: August 29, 1996Date of Patent: September 12, 2000Assignee: Samsung Display Devices Co., Ltd.Inventor: Ji-hoon Lee

Patent number: 6117526Abstract: Conformable strips are constructed from a resilient dimensionally stable material that has a high friction textured top surface. The bottom surface of each strip is coated with a pressure-sensitive adhesive that is used to attach the strip to the exterior surface of the portable computer thereby providing a secure gripping surface to the portable computer. The adhesive permits easy application of the strips to the smooth surface of the computer. The strips are constructed of flexible resilient material so that they can conform to curved flat surfaces when applied thereto. Additional antislip characteristics are obtained by applying successive strips side by side and spaced apart. The openings between the strips provide a multi-edge tread like surface to bind with the hand. Furthermore, the material used to form the strips has sufficient thickness and edge definition to provide a mechanical stop to bind with the flesh of a grasping hand.Type: GrantFiled: October 30, 1996Date of Patent: September 12, 2000Inventor: Ira M. Marks

Patent number: 6110587Abstract: A method is disclosed of producing a blended fabric of polyester and cotton with superior low pilling characteristics. The method comprises polymerizing a melt consisting essentially of terephthalic acid, ethlyene glycol and at least about 1300 parts per million of pentaerythritol to an intrinsic viscosity of at least about 0.55 dl/g. The resulting polymer can be spun into filament, textured, cut into staple, spun into yarn, and formed into fabric. The method and resulting polyester also have advantages in the production of polyester bottle resin and the resulting bottles.Type: GrantFiled: October 14, 1997Date of Patent: August 29, 2000Assignee: Wellman, Inc.Inventors: Billy Mack Humelsine, Carl S. Nichols

Patent number: H1955Abstract: Films, made of polyethylenes and fillers, and articles made therefrom greater WVTR than previously available films based on conventional Ziegler-Natta based polyethylenes. The polyethylenes are produced in a metallocene-catalyzed production process. The films may be made by a cast film process, and may be made in widely varying filler content, generally polyethylene to filler ratios of 30/70 to 70/30. The metallocene based polyethylenes when combined with filler also permit the extrusion of thinner films leading to lighter weight and softer films. The m-polyethylenes utilized for making such films typically have a Composition Distribution Breadth Index above 50%, a Mw/Mn below 3, and a Mz/Mw below 2.Type: GrantFiled: July 31, 1996Date of Patent: April 3, 2001Assignee: Exxon Chemical Patents Inc.Inventors: Jeffrey Alan Middlesworth, Kevin Arthur Brady
