PROBLEM TO BE SOLVED: To provide a printing medium which needs no releasing film. SOLUTION: The printing medium comprises the primer layer 12 and the adhesive layer 13 laminated in this order on the surface of the substrate film 11 treated with friction, and is wound up to produce the roll 15. The weakly adhesive layer 13, which has strong adhesion to the primer layer 12, has weak adhesion to the substrate film 11 in the produced roll 15. Therefore, the printing medium can be wound off the roll 15 to leave no adhesive layer 13 on the roll 15. The weakly adhesive layer 13 can run inside a printing device without using a releasing film. |
