MOLD RELEASE POLYESTER FILM FOR HOT PRESS MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a mold release polyester film for hot press molding suitable as a film for processing, capable of reducing the stainability of a circuit portion and the surface of a circuit during hot press molding, especially during production of the flexible printed circuit board (FPC) and capable of providing mold releasability. SOLUTION: The mold release polyester film for hot press molding is characterized by being obtaining by coating a coating liquid containing a fluorine-containing resin, a block isocyanate crosslinking agent containing polyalkylene glycol chains as essential components onto a polyester film.
