Patent number: 7597956Abstract: A method of fabricating a polymeric film includes adsorbing an ammonium salt surfactant over a plurality of polymer beads. The method also includes adding the polymer beads to a polymer solution, wherein the ammonium salt surfactant substantially prevents flocculation of the polymer beads. Additionally, a polymeric film includes a plurality of polymer beads each having an outer surface. The polymeric film also includes an ammonium salt surfactant disposed over each of the outer surfaces, wherein the ammonium salt surfactant substantially prevents flocculation of the polymer beads.Type: GrantFiled: January 28, 2005Date of Patent: October 6, 2009Assignee: Eastman Kodak CompanyInventors: Roland J. Koestner, Craig T. Mollon, Timothy C. Schunk, William J. Gamble

Patent number: 7252733Abstract: The invention generally relates to polymer films used as protective cover sheets for polarizer plates, a method for producing polarizing plates, and a Liquid Crystal Display employing the same. More particularly, the invention relates to a cover sheet composite having a removable, carrier substrate and a cover sheet comprising a low birefringence polymer film and a layer that promotes adhesion to polyvinyl alcohol on the same side of the carrier substrate as the low birefringence polymer film. The guarded cover sheet of the invention is less susceptible to defects due to dirt and abrasion during the manufacture of the cover sheet and polarizer plates. In addition, the cover sheet has excellent adhesion to polyvinyl alcohol-containing dichroic films and eliminates the need to alkali treat the cover sheet prior to lamination to the dichroic films.Type: GrantFiled: May 4, 2004Date of Patent: August 7, 2007Assignee: Eastman Kodak CompanyInventors: Yongcai Wang, Janglin Chen, Charles C. Anderson, Timothy J. Hubert, Timothy C. Schunk, Richard A. Castle

Patent number: 6767937Abstract: Polymer film, coating, and molded article elements for use in a display device are described which comprise a polymer phase having molecularly dispersed therein an acid scavenger compound, a hindered amine light stabilizer compound and a hindered phenol antioxidant compound, wherein the hindered amine light stabilizer compound and the hindered phenol antioxidant compound are present at a weight ratio of from 20:1 to 1:20, and the weight ratio of the acid scavenger compound to the total concentration of hindered amine light stabilizer compound and hindered phenol antioxidant compound is from 10:1 to 1:10. Use of a combination of an acid scavenger and a combination of two radical scavenger antioxidants dispersed in a polymer phase in accordance with the invention enables enhanced stabilization of the polymer when exposed to high heat and/or humidity condition, which has been found to be especially desirable when applied to polymer layers laminated into displays (e.g., polarizers in liquid crystal displays).Type: GrantFiled: May 17, 2002Date of Patent: July 27, 2004Assignee: Eastman Kodak CompanyInventors: Timothy C.
