ABSTRACT:
Disclosed is a composite film for color copying. The film comprises a printing synthetic resin film with a silica-containing synthetic resin paint coating its front surface. An anti-static agent coats the synthetic resin paint. An adhesive coating is provided on the back surface of the printing film. A base synthetic resin film with a release agent coating its front surface is provided with the release agent layer contacting the adhesive coating on the printing film such that the printing film and the base film are releasably adhered. A silica-containing synthetic resin paint is coated on the back surface of the base film. An anti-static agent is provided on the synthetic resin paint. The synthetic resin paint and anti-static agent coatings on both the printing film and the base film provide the surfaces with a surface resistivity within the range from 1.times.10.sup.8 to 1.times.10.sup.13 ohms, when the surface resistivity is measured at a temperature between 10.degree. C. and 28.degree. C. and the humidity is between 24% and 70%. The surface resistivity of the coated printing film may be less than the surface resistivity of the coated base film.
