Process for producing charge retention medium
To provide a process for producing a charge retention medium, with which a coating film (precursor of a charge retention medium) containing a fluorinated copolymer having repeating units based on tetrafluoroethylene and repeating units based on ethylene can easily be formed on the surface of a substrate, even in a case where the surface of the substrate has a complicated shape.A process for producing a charge retention medium (electret 30), which comprises a step of applying a coating composition containing a fluorinated copolymer (A) having repeating units based on tetrafluoroethylene and repeating units based on ethylene, and an organic solvent (C), to a substrate (first substrate 10) to form a coating film.
