Abstract:
1. A process for producing a surface-modified film, which is characterized by: preparing a halide complex of an element in Group 13 of the periodic table by mixing an oxide of an element in Group 13 with a hydrogen halide or by contacting an anhydrous halide gas of an element in Group 13 with a solvent composed of a compound having a nucleophilic site in the molecule or by mixing an anhydrous liquid or solid halide of an element in Group 13 with a solvent composed of a compound having a nucleophilic site in the molecule; bringing the halide complex of an element in Group 13 of the periodic table into contact with at least a part of a region in the surfaces of a resin film; and washing the resin film with a washing solution at a temperature which is no lower than a melting point of the washing solution, no higher than a boiling point of the washing solution, and no higher than a heat-resistant temperature of the resin film, thereby to produce a surface-modified film having adhesive properties improved in a part of the region in the surfaces.
