Abstract:
The subject invention provides a process for efficiently producing electret coarse powder useful as electrophoretic particles for a large-screen display.The process for producing electret coarse powder comprises irradiating a fluorine-containing resin sheet with an electron beam or a radial ray to convert the fluorine-containing resin sheet into an electret sheet, and pulverizing the electret sheet.
