A film having an antistatic releasing agent layer comprising fiber-shaped carbon and disposed on at least one of the faces of a substrate film, a release film having a releasing agent layer disposed on one face of a substrate and an antistatic layer which comprises a cured product of a resin composition of the active energy ray curing type comprising fiber-shaped carbon or a combination of fiber-shaped carbon and an electrically conductive macromolecular compound and is disposed on the other face of the substrate film, and processes for producing the films. The release films have a relatively small thickness of the antistatic layer, exhibit the stable antistatic function, are excellent in smoothness, do not adversely affect hardening of the resin releasing agent, exhibit the excellent releasing function and provide the excellent productivity.
A release film which comprises an antistatic layer comprising fiber-shaped carbon and a substrate film, wherein the fiber-shaped carbon is disposed on at least one face of the substrate film.
A process for producing a release film which comprises coating at least one face of a substrate film with a coating fluid comprising a releasing agent and fiber-shaped carbon to form a coating layer and drying the coating layer to form an antistatic releasing agent layer.
A process for producing a release film which comprises forming an antistatic layer on one face of a substrate film by coating the face with a resin composition of an active energy ray curing type comprising fiber-shaped carbon to form a coating layer, drying the coating layer to form a coating film and irradiating the coating film with an active energy ray to cure the coating film, and forming a releasing agent layer on an other face of the substrate film by coating the other face with a coating fluid comprising a releasing agent and drying the coating fluid to form a layer.
