Patent number: 11231536Abstract: A polarizer including an oriented polymeric first layer is described. The oriented polymeric first layer is preparable from a mixture of polyvinyl alcohol and crosslinker where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, in that for U=(1/MDDR?1)/(TDDR1/2?1), U is at least 0.85, with MDDR being a machine direction draw ratio and TDDR being a transverse direction draw ratio.Type: GrantFiled: August 3, 2017Date of Patent: January 25, 2022Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Kristy A. Gillette, James E. Lockridge, Brianna N. Nieson, Joan M. Noyola, Jason S. Petaja, Matthew B. Johnson, Jeffrey W. Hagen

Publication number: 20210302628Abstract: A coating composition includes a first polymer and a second polymer that are incompatible and non-reactive with one another. The absolute value of the difference between the refractive index of the first polymer and the refractive index of the second polymer is about 0 to about 0.01. The first polymer and the second polymer are soluble in a carrier liquid that is a good solvent for the first polymer and a poor solvent for the second polymer. The carrier liquid is removed from the coating layer to spinodally decompose the mixture of the first polymer and the second polymer in an amount sufficient to form a substantially continuous first phase with a predominant amount of the first polymer and a substantially discontinuous second phase with a predominant amount the second polymer. At least 70% of the second phase includes droplets with an aspect ratio, when viewed in the plane of the surface of the substrate, of less than about 3.Type: ApplicationFiled: May 27, 2021Publication date: September 30, 2021Inventors: Thomas J. Ludemann, Jeffrey W. Hagen, David T. Ask, Kristy A. Gillette, Eric D. Shockey

Patent number: 9915762Abstract: A sheet comprising: (1) a core member comprising one or more layers and having a first major surface and (2) a slip control layer disposed on at least a portion of the first major surface, wherein the slip control layer comprises: (i) a footing layer disposed on at least a portion of the first major surface of the core member, (ii) a binder layer disposed on the footing layer, and (iii) an array of particles disposed in the binder layer and footing layer and protruding therefrom, wherein the average diameter of the particles is greater than the combined thickness of the foot layer and binder layer.Type: GrantFiled: August 20, 2013Date of Patent: March 13, 2018Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Kristopher J. Derks, Jeffrey W. Hagen, James E. Lockridge, Jeffrey A. Peterson, Brent A. Hedding

Patent number: 9895837Abstract: A textured film, a process for manufacture of the textured film, and a light management stack, a backlight, and a display using the textured film are described. The textured film and process for manufacture thereof, include processes in which the surface texture of the optical film is controlled by incorporation of a patterned coating. The surface texture of a polymeric film, such as a polymeric optical film, is controlled by incorporation of the coating, that can fracture or deform upon stretching the film.Type: GrantFiled: September 13, 2012Date of Patent: February 20, 2018Assignee: 3M Innovative Properties CompanyInventors: Kristopher J. Derks, James E. Lockridge, Adam D. Haag, Jeffrey A. Peterson, Michael J. Schiesl, Jeffrey W. Hagen

Patent number: 9102131Abstract: A textured film, a process for manufacture of the textured film, and a light management stack, a backlight, and a display using the textured film are described. Generally, the surface texture of a polymeric film, such as a polymeric optical film, is controlled by incorporation of a fracturable coating that fractures upon stretching the film.Type: GrantFiled: March 16, 2011Date of Patent: August 11, 2015Assignee: 3M Innovative Properties CompanyInventors: Kristopher J. Derks, Jeffrey W. Hagen, James E. Lockridge, Michael J. Schiesl, Adam D. Haag, Jeffrey A. Peterson, Stephen A. Johnson, Mark J. Pellerite, Michael L. Steiner, Hang K. Loi

Publication number: 20090074976Abstract: The invention provides methods of reducing visible defects in curable coating compositions. In one embodiment, the method includes coating a curable composition onto a substrate, removing solvent from the curable composition, and heating the dried curable composition to a temperature at which the curable coating exhibits leveling flow. In another embodiment, the curable composition is coated onto a substrate, and then is heated to a temperature at which the curable coating exhibits leveling flow.Type: ApplicationFiled: July 17, 2008Publication date: March 19, 2009Inventors: Anthony J. Freking, Jeffrey W. Hagen, Thomas J. Ludemann, Kevin G. Moseley, Richard J. Pokorny, Steven D. Solomonson, Robert A. Yapel
