Kind Code:
A
Abstract:
To provide a transparent base film for an adhesive tape, which is superior in ultraviolet light transmittance.SOLUTION: A UV-curable type film for an adhesive tape base comprises thermoplastic resin composition, which is 80% or larger in UV transmittance at a wavelength of 365 nm and which is transparent. In addition, the film is 1.0 or below in internal haze.EFFECT: Thus, a film for a base, which can satisfactorily lower the adhesion of an adhesive tape after UV exposure to facilitate the peeling of the adhesive tape, and therefore decrease a residue of the adhesive tape on an adherend, can be obtained.SELECTED DRAWING: None
