Patent number: 7986450Abstract: A polyurethane formed from an isocyanate, a polyether diol and a polyester diol, the polyester diol having a molecular weight less than about 2000, or comprising two polyester diol segments connected by a steric hindrance group, each of the polyester diol segments having a molecular weight less than about 2000, the molar ratio of polyether diol to polyester diol being in the range of from about 1:9 to about 9:1. The polyurethane is useful as a lamination adhesive in electro-optic displays, and in components used to form such displays.Type: GrantFiled: January 12, 2009Date of Patent: July 26, 2011Assignees: E Ink Corporation, Air Products and Chemicals, Inc.Inventors: Lan Cao, David D.

Patent number: 7910175Abstract: A coating of an encapsulated electrophoretic medium is formed on a substrate (106) by dispersing in a fluid (104) a plurality of electrophoretic capsules (102), contacting at least a portion of a substrate (106) with the fluid (104); and applying a potential difference between at least a part of the portion of the substrate (106) contacting the fluid (104) and a counter-electrode (110) in electrical contact with the fluid (104), thereby causing capsules (102) to be deposited upon at least part of the portion of the substrate (106) contacting the fluid (102). Patterned coatings of capsules containing different colors may be deposited in registration with electrodes using multiple capsule deposition steps. Alternatively, patterned coatings of capsules may be formed by applying a fluid form of an electrophoretic medium to a substrate, and applying a temporally varying voltage between an electrode and the substrate. The process may be repeated to allow for deposition of full color displays.Type: GrantFiled: August 3, 2007Date of Patent: March 22, 2011Assignee: E Ink CorporationInventors: Richard M.
