Publication number: 20210071043Abstract: The present disclosure relates to adhesive article that include a stretch releasable adhesive and topographical, engineered elements on, within, or partially embedded in a surface of the adhesive. The engineered elements can act as spacers between the adhesive surface and the mounting surface to prevent full contact and wet out of the adhesive, whereby the article can be initially positioned or rotated by sliding the surface of the projections across the wall surface. Under certain conditions, the article may even be removed from the wall and placed at a new location without damage to the wall surface or the article. Once the location is selected, the separation created by the engineered elements can be overcome by applying sufficient pressure; the adhesive can contact and adhere more permanently to the wall.Type: ApplicationFiled: May 8, 2019Publication date: March 11, 2021Inventors: Payam Khodaparast, Nishant C. Kumar, Joseph A. Hoffman, Margaret M. Sheridan, Guy M. Kallman, Sara Hemmer Frisco, Nicholas A. Lee, Ann M. Gilman, Matthew R. D. Smith

Publication number: 20160290599Abstract: A luminaire is provided which includes an LED light source and a reflector that includes a semi-specular reflective film. The semi-specular reflective film has a transport ratio (TR) of between 40% and 70% and a reflectivity of greater than 95% and comprises a multilayer optical film (MOF), a an ultra-low index (ULI) layer having a refractive index of less than 1.3, and a diffusing layer (DL) borne on the reflecting face of the semi-specular reflective film. The LED light source and reflector are in fixed arrangement such that the luminaire may be arranged relative to an architectural surface such that 75% or more of visible light emerging from the LED light source strikes the reflector and subsequently strikes the architectural surface without reflection off of any other surface nor transmission through any medium other than ambient air.Type: ApplicationFiled: December 16, 2014Publication date: October 6, 2016Inventor: Guy M. Kallman

Publication number: 20020110685Abstract: A tie layer film, comprising an admixture of polyvinyl alcohol and a water dispersible polyester, for bonding a support film to a topcoat layer. The preferred tie layer comprises a sulfopolyester, preferably including terephthalate groups or isophthalate groups. Most preferred are sulfopolyesters produced from ingredients comprising monomers selected from the group consisting of dimethyl 5-sodiosulfoisophthalate, dimethyl terephthalate, dimethyl isophthalate, ethylene glycol, and polycaprolactone diol. Alternatively the support film may be a layered film. In a preferred embodiment, the topcoat layer is formed from the same PVA material as the tie layer and the support film includes at least a portion of the same sulfopolyester as the tie layer. The tie layer is capable of maintaining the bond between the support film and the topcoat layer when heat stretched to a stretch ratio in the range of 2 times to 10 times its original dimension.Type: ApplicationFiled: February 9, 2001Publication date: August 15, 2002Inventors: Ikuko Ebihara, Guy M. Kallman, Gregory E. Gilligan, William L. Kausch, Brian H. Williams, Robert W. Horn

Patent number: 6268961Abstract: An optical film includes a reflective polarizing element and a particle-containing layer. The reflective polarizing element substantially reflects light having a first polarization state and substantially transmits a second polarization state. The particle-containing layer is disposed on the reflective polarizing element and in a same optical path as the reflective polarizing element. The particle-containing layer is configured and arranged to transmit light and includes a plurality of particles that roughen an exterior surface of the optical film. Preferably, using the optical film in an optical device does not substantially reduce the gain advantage of the optical device when compared with an optical device utilizing the same optical film without particles in the surface layer. Also described are optical devices using the optical film and methods of making and using the optical films.Type: GrantFiled: February 4, 2000Date of Patent: July 31, 2001Assignee: 3M Innovative Properties CompanyInventors: Timothy J.
