PURPOSE: To obtain a film for peeling a marking from which a bonded marking sheet can be easily and safely peeled off by providing a softening agent layer contg. a plasticizer having compatibility with a marking sheet-forming polymer on a base material sheet.

CONSTITUTION: As a film for peeling a marking sheet, a softening agent layer 3 is provided on a base material film 2 and a plasticizer is incorporated in the softening agent layer 3. As this plasticizer, such a plasticizer that has compatibility with a polymer forming a base material 5 of a marking sheet 4 which is usually polyvinyl chloride, vinyl chloride copolymer or vinyl acetate polymer is used and such a plasticizer that, has large migration and volatility is pref. In addition, such an oil and a surface active agent that has compatibility or swelling properties with a print displaying part 8 and a strongly pressure- sensitive adhesive layer 6 of the marking sheet 4 and such a polymer that has compatibility with the plasticizer may be used in parallel. This softening agent layer 3 is adhered on the adhered marking sheet 4 and then peeled off. In this case, if it is heated, peeling time can be shortened.
