More Information
Summary:Provided is a transfer film that transfers recesses and projections to a protective layer of an electromagnetic wave shield film, thereby successfully imparting a matte effect to the surface of the protective layer, and that can be used to produce an electromagnetic wave shield film in which cracks do not easily occur in the protective layer during thermocompression bonding. This transfer film is provided with a matte effect transfer layer having a matte effect transfer surface, and is characterized in that the matte effect transfer layer comprises a resin filler.
