Abstract
A printing medium is manufactured by forming a primer layer and an adhesive layer successively on the rubbed surface of a base film and wound into a roll When the printing medium is delivered from roll adhesive layer does not remain on the roll side even if adhesive layer has a low adhesive power because the adhesion between adhesive layer and primer layer is strong while the adhesion between adhesive layer and base film in roll is weak. The printing medium can be run in a printer without using a release film because adhesive layer has a low adhesive power.
