摘要： A water base pigment ink for ink-jet recording contains a pigment, water, and at least one of polyethylene glycol and diglycerol. The ink is solidified into a solid matter when the water is evaporated. Further, the solid matter is redissolved in the unsolidified water base pigment ink for ink-jet recording. When the ink is used, then neither clog-up of a nozzle nor discharge failure is caused, no load is imposed by the solidified ink on the maintenance system such as the wiping equipment, and the sticking performance on the paper is satisfactory.

摘要： A display medium includes a pair of substrates, a spacer, an injection port, and an exhaust port. The pair of substrates faces to be in parallel with each other. At least one of the pair of substrates constitutes a display surface. The spacer is disposed between the pair of substrates to form a fluid chamber together with the pair of substrates. The fluid chamber encapsulates a fluid material and has a polygonal shape in a cross section taken parallel to the display surface. The polygonal shape has two acute corners each having an angle greater than 0° and no greater than 75°. The fluid material flows in accordance with electric fields generated between the pair of substrates to display images on the display surface. The fluid material is injected into the fluid chamber through the injection port. Air in the fluid chamber is exhausted outside the fluid chamber through the exhaust port. A distance between one of the injection port and the exhaust port and one of the two acute corners as viewed from a direction orthogonal to the substrate is equal to or smaller than 5 mm.

摘要： A display medium includes a first substrate constituting a display surface, a second substrate disposed in opposition to the first substrate for forming a fluid chamber between the first and the second substrates, and a partition wall member for dividing the fluid chamber into a plurality of cells. The plurality of cells is filled with an electrophoretic medium wherein a charged particle dispersion including an organic solvent with dispersed charged particles is dissolved or dispersed in a dispersion medium. An image is displayed on the display surface by moving the charged particles based on the directions of electric fields generated between the first substrate and the second substrate. The manufacturing method includes a filling step for filling the plurality of cells with the charged particle dispersion before the partition wall member is covered with the first and second substrates, a subsequent injection step for injecting the dispersion medium for dissolving or dispersing the charged particle dispersion into the plurality cells.
