The composition can also include a dispersing agent to disperse the gas bubbles throughout the composition.Type: GrantFiled: August 30, 2004Date of Patent: February 6, 2007Assignee: Ultradent Products, Inc.Inventors: Jeff A. Wagner, Neil T. Jessop

Microencapsulated pigment, production process therefor, aqueous dispersion and ink jet recording ink
Patent number: 7074843Abstract: Provided are ink jet ink excellent in dispersion stability and ejection stability and capable of forming images with fastness, abrasion resistance, color developability, and high density with little feathering; a microencapsulated pigment (MCP) providing the ink and a process of making the same; and an aqueous dispersion of the MCP. The MCP comprises pigment particles having a hydrophilic group on their surface (hydrophilized pigment particles) and coated with a polymer by emulsion polymerization. The process comprises emulsion polymerization in the presence of the hydrophilized pigment particles. The ink essentially contains the MCP and water.Type: GrantFiled: August 26, 2002Date of Patent: July 11, 2006Assignee: Seiko Epson CorporationInventors: Hiroto Nakamura, Toshiyuki Miyabayashi, Masahiro Yatake, Hidehiko Komatsu -
