  • Microcapsules for electrophoretic display devices, and processes for their production, and their applications
    Patent number: 8174755
    Abstract: The microcapsules for electrophoretic display devices according to the present invention each enclose a dispersion containing electrophoretic particles and a solvent in a shell having an inner shell made of a mercapto group-containing amino resin and an outer shell made of an epoxy resin. Alternatively, the microcapsules for electrophoretic display devices according to the present invention each have a capsule strength of 0.6 MPa or higher. These microcapsules are produced by dispersing a dispersion containing electrophoretic particles and a solvent as a core substance in a water-based medium, and subsequently forming at least one shell on the surface of the core substance. These microcapsules can be used, as their applications, for sheets for electrophoretic display devices, electrophoretic display devices using the sheets, and electronic equipments using the electrophoretic display devices.
