PROBLEM TO BE SOLVED: To obtain excellent slip properties without damaging printing quality by providing a porous ink receiving layer on one surface of a base material sheet and partially bonding a solidified film of printing ink to the other surface thereof. SOLUTION: When ink films are bonded to the rear surface of a base material sheet in regular patterns, slip properties between recording sheets become uniform and, therefore, this bonding method is pref. but the ink films may be bonded in irregular patterns. As the regular patterns, geometric patterns such as checkered patterns, polka-dot patterns or checked patterns or patterns wherein company names or commodity names or logomarks of them are regularly arranged are designated. There is no special limit in the color of the ink films and various colors can be employed or transparent ink films can be employed. In the case of the transparent base material sheet, it is pref. to form a transparent ink film to the entire surface of the sheet. For example, printing ink is bonded to the base material sheet by a gravure printing method and dried and solidified to form an ink film. |
