Abstract
Provided is a coating for forming a conductive release layer capable of forming a conductive release layer having high adhesion to a film base material, suppressing deterioration in conductivity over time in the air, and having a sufficient releasing property. The coating for forming a conductive release layer of the present invention contains a conductive composite including a π-conjugated conductive polymer and a polyanion, an epoxy compound having an epoxy group, a curable silicone, a polyester resin, and an organic solvent.
Claims19
A coating for forming a conductive release layer comprising:
- a conductive composite including a π-conjugated conductive polymer and a polyanion;
- an epoxy compound having an epoxy group;
- a curable silicone;
- a polyester resin;
- and
- an organic solvent.
A method for producing a coating for forming a conductive release layer, the method comprising:
- a precipitation recovery step of adding an epoxy compound having an epoxy group to an aqueous dispersion in which a conductive composite containing a π-conjugated conductive polymer and a polyanion is included in an aqueous dispersion medium and precipitating a conductive composite to obtain a precipitate and then recovering the precipitate;
- and
- an adding step of adding an organic solvent, a curable silicone, and a polyester resin to the recovered precipitate.
A conductive release film comprising:
- a film base material;
- and
- a conductive release layer formed on at least one surface of the film base material,
- wherein the conductive release layer contains a conductive composite including a π-conjugated conductive polymer and a polyanion, an epoxy compound having an epoxy group, a silicone, and a polyester resin, and the epoxy compound having an epoxy group is bonded to the anion group of a part of the polyanion.
