Abstract
A surface protective film comprising a base film and a resin film thereon can be bonded to a substrate having a circuit-forming surface and separated therefrom after processing. The resin film is formed of a resin composition comprising (A) a silphenylene-siloxane skeleton-containing resin, (B) a compound capable of reacting with an epoxy group in the resin to form a crosslinked structure, (C) a curing catalyst, and (D) a parting agent.
