OPTICAL SURFACE PROTECTIVE FILM WITH SEPARATOR

摘要

Provided is an optical surface protective film with a separator comprising: a polyester film on one surface of an adhesive layer; and the separator on the surface opposite the polyester film of the adhesive layer; wherein an Si-K alpha x-ray strength in a fluorescent x-ray of the surface of the adhesive layer after peeling the separator is at most 2.5 kcps; and wherein a peeling force of the separator with respect to the optical surface protective film is at most 0.5 N/50mm in a tension speed of 0.3 m/minute. The optical surface protective film with the separator can prevent the phenomenon of other layers provided on the surface of the adherend, such as an interlayer filler (layer), from peeling easily after peeling the surface protective film from the adherend.
