ABSTRACT:
Disclosed herein is a display composition which comprises a dye and a clay mineral in which quaternary ammonium ions are bound between layers through ion exchange, said display composition undergoing reversible color development and color fading through the oxidation and reduction of said dye, the oxidation causing said dye to form a color and to be bound between the layers of said clay mineral through ion exchange with said quaternary ammonium ions, the reduction causing the dye to discolor and to be desorbed out of the interlaminar space of the clay mineral and also causing the quaternary ammonium ions to be bound again between the layers through ion exchange. Disclosed also herein are a coloring pigment and recording material which employ the display composition.
