Patent number: 7081300Abstract: A decorative laminate assembly having a decorative laminate top layer assembly. This top layer assembly includes, in descending superimposed relationship, a decorative layer and a core layer that includes PETG, or other polymeric material. Preferably, the top layer assembly also includes a wear resistant overlay layer on top of the decorative layer, and the core layer's PETG is in a sheet form. The top layer assembly may be directly bonded to a water resistant substrate. The decorative laminate assembly of the present invention can be used for a variety of purposes, including flooring applications. When the present invention is used for flooring applications, it is preferred that the overlay layer has enhanced wear resistant qualities and that the water resistant substrate comprise PVC or cement fiberboard.Type: GrantFiled: September 18, 2001Date of Patent: July 25, 2006Assignee: Formica CorporationInventors: Kenneth John Laurence, Terry Paul Drees, Kevin Francis O'Brien, Bob Fairbanks

Patent number: RE41539Abstract: A breathable composite sheet material, a method for making such a sheet material, and an absorbent article utilizing the sheet material are provided. The composite sheet material is comprised of a thermoplastic film adhered directly to a fibrous substrate. The thermoplastic film comprises at least 50% by weight of a polymer material from the group of block copolyether esters, block copolyether amides and polyurethanes. The substrate comprises a fibrous web of at least 50% by weight of polyolefin polymer synthetic fibers. The composite sheet exhibits a peel strength of at least 0.1 N/cm, a dynamic fluid transmission of less than about 0.75 g/m2 when subjected to an impact energy of about 2400 joules/m2, and a moisture vapor transmission rate, according to the desiccant method, of at least 1500 g/m2/24 hr.Type: GrantFiled: January 31, 2008Date of Patent: August 17, 2010Assignee: The Procter & Gamble CompanyInventors: Nora Liu Carroll, Hyun Sung Lim, George Joseph Ostapchenko, Shailaja R.
