The present invention relates to a resin composition, to a multilayer film, to a back sheet for a photovoltaic module, to a method for manufacturing same, and to a photovoltaic module. According to the present invention, since a multilayer film is formed by coating a cured resin composition material, which includes a fluorinated polymer, an acrylic polymer containing a thermosetting functional group, and a thermal curing agent, onto a base material, the coating layer containing the fluorinated polymer may have superior durability and weather-proofing properties, and further high interface adhesion with the base material may be obtained. Also, since drying is performed at a low temperature during the process of manufacturing the multilayer film, manufacturing costs may be reduced and productivity may be increased. In addition, deterioration in product quality due to thermal deformation or thermal impact may be prevented. As described above, the multilayer film may be effectively utilized ...
