Beschreibung
Zusammenfassung:	A resin film comprising a multilayer structure acrylic polymer and the film having an acid value of not more than 0.018 mmol/g in an acetone insoluble matter, an acid value of not more than 0.012 mmol/g in an acetone soluble matter, a glass transition temperature of not less than 80°C and a thickness of 5 to 300 µm is obtained by a method comprising emulsion polymerization for producing a latex comprising multilayer structure acrylic polymer, coagulating the latex comprising the multilayer structure acrylic polymer to obtain a slurry, washing and dehydrating the slurry, drying the dehydrated slurry to remove the multilayer structure acrylic polymer, mixing 0 to 35 % by mass of an acrylic resin and 65 to 100 % by mass of the removed multilayer structure acrylic polymer and subjecting the resultant mixture melted to an extrusion molding.
