US Patent:

20030059578, Mar 27, 2003
Filed:

May 31, 2001
Appl. No.:

09/871421
Inventors:

Todd Williams - Lake Elmo MN, US
Olester Benson - Woodbury MN, US
Assignee:

3M Innovative Properties Company
International Classification:

B32B003/30
US Classification:

428/172000, 428/173000, 264/485000, 264/495000, 264/496000, 264/171140
Abstract:

A composite article having large scale predictable dimensional stability comprises a metal foil backing having adhered thereto a layer of cured polymer having an exposed surface bearing a three-dimensional microstructure of precisely shaped and located functional discontinuities. The article is made by depositing a layer of a radiation curable composition onto a metal foil backing, contacting a master with a pattern capable of imparting a three-dimensional microstructure of precisely shaped and located functional discontinuities into the layer of radiation curable composition, while the layer of radiation curable composition is in contact with the master, exposing the curable composition to radiation to cure the composition, and separating the cured polymer layer on the metal foil backing from the surface of the master. Either the metal foil backing or the master may be radiation transmissive.

Filed:

Feb 19, 2003
Appl. No.:

10/369014
Inventors:

Michael Weber - Shoreview MN, US
Olester Benson - Woodbury MN, US
Sanford Cobb - St. Mary's Point MN, US
James Jonza - Round Rock TX, US
Andrew Ouderkirk - Woodbury MN, US
David Wortman - St. Paul MN, US
Carl Stover - St. Paul MN, US
Assignee:

3M Innovative Properties Company
International Classification:

G02F001/1335
US Classification:

349/115000
Abstract:

A multiple layer reflective polarizer is described. This element is placed between and optical cavity and an LCD module to form an optical display. The reflective polarizer reflects some light into the optical cavity where it is randomized and may ultimately emerge with the correct polarization to be transmitted out of the display.

International Classification:

E06B003/24
US Classification:

428/034000, 428/167000
Abstract:

An assembly including a polymeric film and an effective amount of an ultraviolet light-absorbing compound in an inert environment.

International Classification:

A61B001/24
US Classification:

433/030000
Abstract:

Dental articles including at least one optical surface formed of a multilayer optical film including layers of at least one strain-induced birefringent material are disclosed. The multilayer optical films included in the dental articles is preferably post-formed into desired non-planar shapes in manners that result in some deformation of the optical stack of the multilayer optical films. A variety of dental implements can be constructed with multilayer optical film including dental mirrors, light guides for use in connection with photo-curing dental materials, and matrix bands for use in molding photo-curing dental restoratives.
