COMPOSITE FILM FOR COATING MATERIAL USED BY COATING ON OBJECTS RECEIVING BENDING DEFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a composite film for a coating material of which film deforms with following bending when coating objects to be coated by the film receive bending deformation after coating, and hardly peeling off the film at deformation, and to provide an adhesive tape using the film.SOLUTION: There is provided a composite film for a coating material used by coating on objects receiving bending deformation, having 20% tensile loads of 3 N/25 mm or less, elastic modulus of 0.2 to 15 MPa, viscosity of 0.1 to 25 GPa s and the glass transition temperature of 15°C or lower. There is also provided an adhesive tape using the composite film for the coating material.
