Publication number: 20130288052Abstract: Adhesive compositions, including pressure sensitive adhesives, are the reaction product of free radically polymerizable mixtures. The free radically polymerizable mixtures include a free radically polymerizable urethane-based or urea-based oligomer, a free radically polymerizable segmented siloxane-based copolymer, and an initiator. The free radically polymerizable mixture may contain additional reactive and/or unreactive additives. The adhesive compositions can be used to prepare a variety of adhesive articles.Type: ApplicationFiled: October 31, 2011Publication date: October 31, 2013Applicant: 3M Innovative Properties CompanyInventors: Scott M. Tapio, Joan M. Noyola, Michael K. Gerlach, Jeffrey A. Keith

Patent number: 7846541Abstract: An optical element includes a polarizer having oriented vinylene segments; a substrate; and an adhesive layer disposed between the polarizer and the substrate, the adhesive layer comprising aliphatic urethane(meth)acrylate oligomer, (meth)acryl monomer, silane, and crosslinker, the crosslinker comprising ethylene glycol diacrylate and/or pentaerythritol triacrylate. The optical element can have additional layers such as hardcoat layers, additional adhesive layers, and/or additional substrates. A method of making the optical element is also disclosed, as are optical devices including the optical element.Type: GrantFiled: November 2, 2007Date of Patent: December 7, 2010Assignee: Seiko Epson CorporationInventors: Xuequn Hu, Pradnya V.

Patent number: 7643211Abstract: An intrinsic polarizer, including a sheet of PVA-type matrix that includes vinylene polymer blocks, the sheet defining a pass polarization axis and a block polarization axis perpendicular to the pass polarization axis, light having an electrical vector parallel to the pass polarization axis being substantially transmitted through the sheet and light having an electrical vector parallel to the block polarization axis being substantially absorbed by the vinylene blocks, the sheet exhibiting a dichroic ratio of more than 100.Type: GrantFiled: December 19, 2008Date of Patent: January 5, 2010Assignee: Seiko Epson CorporationInventors: Michael K. Gerlach, Gerald N. Nkwantah, Jonathan M. Mack, Pradnya V. Nagarkar, Philip J. Ralli

Patent number: 7573637Abstract: An improved method of forming an intrinsic polarizer, referred to as a K-type polarizer, includes stretching a polymeric film a first stretching step. The polymeric film comprises a hydroxylated linear polymer which is converted after the first stretching step to form dichroic, copolymer polyvinylene blocks aligned in the polymeric film. The polymeric film is stretched in a second stretching step while converting the hydroxylated linear polymer. This method produces an improved K-type polarizer with excellent polarizing and color characteristics. For example, the dichroic ratio is higher than 100, the color shift for light passed through the polarizer in a crossed configuration is low, and the absorption of light in the blue region of the visible spectrum is more than one half of the absorption for light in the middle of the visible spectrum.Type: GrantFiled: August 3, 2004Date of Patent: August 11, 2009Assignee: Seiko Epson CorporationInventors: Michael K. Gerlach, Gerald N. Nkwantah, Jonathan M. Mack, Pradnya V. Nagarkar, Philip J. Ralli

Publication number: 20090163686Abstract: An integrated wet stretch method of making an intrinsic polarizer includes the following steps in order: providing a polymeric film comprising poly(vinyl alcohol) and having an original length; immersing the polymeric film in a first bath comprising a first solution having a pH of less than about 3; uniaxially stretching the first polymeric film in the machine direction thereby forming a stretched polymeric film; removing the stretched polymeric film from the first bath; removing excess first solution from the stretched polymeric film; and uniaxially stretching the stretched polymeric film in the machine direction, at a temperature of at least about 120° C., thereby forming a further stretched polymeric film.Type: ApplicationFiled: December 20, 2007Publication date: June 25, 2009Inventors: Michael K. Gerlach, Gerald N. Nkwantah, Giorgio B. Trapani, Pradnya V. Nagarkar, Phillip J. Ralli
