Abstract: The present invention provides a method and a device for manufacturing a card, capable of arbitrarily printing characters and designs on an ink receiving layer after molding the card by injection molding. The card is manufactured by joining an ink receiving layer (2) formed on a base material sheet (4a) to a card base (1) when molding the card base (1) by filling an injection-molding resin (10) in a cavity (7) of a metal mold (5), and after this by peeling the base material sheet (4a). A desired printing is applied to the card on its ink receiving layer (2) by an ink-jet printer or the like after the card is taken out from the metal mold (5).

Abstract: Novel molten-salt type polyelectrolytes are disclosed which contain as an essential ingredient a molten salt polymer obtained by reacting an imidazolium derivative, such as a 1,3-dialkylimidazolium halide, 1,2,3-trialkylimidazolium halide, 1-vinyl-3-alkylimidazolium halide, or 1-vinyl-2,3-alkylimidazolium halide, with an acid monomer, a poly(vinylsulfonamide), trifluoromethanesulfonimide, or the like. The electrolytes show high ionic conductivity at room temperature and have excellent stability to temperature fluctuations and excellent mechanical properties.
