PURPOSE:To obtain a highly reliable print image by providing an ink layer consisting mainly of a copolymer of a coloring agent, (metha) acrylonitrile and glycidyl (metha) acrylate as principal constituents on a base. CONSTITUTION:Comparatively highly heat-resistant plastic film, such as polyester or polycarbonate,or cellophane and sulfated paper for example, are used as a base. ln addition, carbon black, organic pigment, inorganic pigment or any selected dye are used as coloring agents. Methaacrylnitrile- glycidylmethacrylate, acrylonitrileglycidylmethacrylate which are copolymers based on (metha) acrylonitrile and glycidyl (metha) acrylate are used as principal materials for an ink layer. These materials are compounded ae specified and this compound is applied to the base and then is dried. Consequently, the image becomes significantly highly resistant against abrasion, heat and various chemicals. Thus a highly reliable print image is obtained. |
