COATING FILM STRUCTURE HAVING STUCK TAPE LAYER

摘要

PROBLEM TO BE SOLVED: To prevent the exfoliation of a tape stuck onto the surface of a coating film formed on a body sealer. SOLUTION: A urethane-based exfoliation preventing film 5 is formed between a body sealer layer 3 and an intermediate coating film 4 and/or between the intermediate coating film 4 and a top coating film 6. Since the film 5 controls the migration of a plasticizer contained in the layer 3 and prevents its bleeding, a tape layer 7 is prevented from being peeled off.
