PURPOSE:To attain to enhance the adhesiveness between a support and a medium layer, by forming a three-layered structure consisting of a plastic support layer, an adhesive layer and an electrophoretic medium layer comprising a polyacrylamide type aqueous gel. CONSTITUTION:A plastic support layer and an electrophoretic medium layer comprising a polyacrylamide type aqueous gel are adhered by an adhesive layer formed of an amido group-containing grafted derivative of a methyl methacrylate macromonomer to form a three-layered structure. In this structure, said three-layered structure becomes hard to separate even by various operations in the dyeing process of the medium layer. |
