Publication number: 20080096008Abstract: The present invention is an electrophotographic transfer paper having a coating layer containing a pigment and a binder on at least one side of a base paper comprising a pulp and a filler, and excellent transport characteristics in high-speed copy machines and printers. 30 wt % or more of the pigment is kaolin having a particle size distribution wherein 65% or more particles are in a range of 0.4-4.2 ?m based on volume, and/or delaminated clay having an average particle size of 3.5-20 ?m. The clark stiffness in the CD direction of the electrophotographic transfer paper is 20 cm3/100 or more.Type: ApplicationFiled: September 29, 2005Publication date: April 24, 2008Inventors: Jiro Yoshimura, Hisahiro Omote, Masahito Suzuki, Koji Okomori, Dai Nagahara

Publication number: 20080041542Abstract: Polymer composite films were prepared by solvent casting suspensions of quantum dots (QDs) in cellulose triacetate (CTA) solution. The films were robust and possessed the optical properties characteristic of QDs. Transmission electron microscopy (TEM) images of the films revealed that the QDs were well dispersed within the CTA film matrix. The selective alkaline hydrolysis of QD/CTA films in 0.1N NaOH over 24 hours resulted in the surface conversion of CTA to regenerated cellulose. Optical properties of the films were probed both before and after the hydrolysis reaction using fluorescence spectroscopy, and were found generally unaltered. The cellulose surfaces of the alkaline treated films allow for facile incorporation of the films into paper sheets.Type: ApplicationFiled: February 7, 2007Publication date: February 21, 2008Inventors: Derek Gray, Tiffany Abitbol

Patent number: 7320825Abstract: A multi layer composite having oil and grease resistance comprising: a) a paper or paperboard substrate, b) a base coat on a surface of said substrate comprising a first polymer selected from the group consisting of film forming natural and synthetic polymers in the substantial absence of a mineral pigment filler, and c) a top coat on a surface of said base coat, said top coat comprising a continuous polymer phase comprising one or more film forming synthetic polymers having dispersed therein at least one platy mineral pigment and at least one non-platy mineral pigment. This invention also relates to a method of making the composite and articles of manufacture fabricated totally or in part from the composite of this invention where oil and grease resistance is required or desired, such as container, bags and wraps for packaging oily or greasy materials such as animal and human food.Type: GrantFiled: May 27, 2003Date of Patent: January 22, 2008Assignee: International Paper CompanyInventor: Patrick Morabito

Publication number: 20080014433Abstract: A composite wood product is manufactured by heating and pressing wood materials in contact with a mixture of resin and urea. Gases that evolve from the heating and pressing of the wood materials, resin and urea are collected and are passed through a biological oxidation system to remove volatile organic compounds.Type: ApplicationFiled: July 10, 2007Publication date: January 17, 2008Applicant: BIO-REACTION INDUSTRIES, LLCInventors: Baron V.
