MOLD RELEASE COMPOSITION AND SURFACE PROTECTIVE FILM

摘要

Provided is a mold release composition, with which it is possible to form a transparent coating on the surface of which a photoresist cannot be readily deposited. Also provided is a surface protective film having a coating formed from the cured product of the mold release composition. The mold release composition comprises a binder resin, a silicone oil, and a metal alkoxide hydrolysis product. Preferably the metal alkoxide hydrolysis product content is 50 to 500 parts by weight per 100 parts by weight of binder resin. Preferably the metal alkoxide consists of tetraethoxysilane or tetramethoxysilane. The surface protective film is obtained by forming a coating of the cured product of the mold release composition on a substrate.
