PROBLEM TO BE SOLVED: To provide a resin multilayered film having one layer comprising a styrenic resin, useful as a phase difference film and good in adhesiveness even if an adhesive layer is not used, and to obtain the negative phase difference film by stretching the resin multilayered film. SOLUTION: The resin multilayered film is constituted by laminating a first layer with a thickness of 10-100μm comprising the styrenic resin and a second layer with a thickness of 10-100μm comprising an acrylic resin composition compounded with a rubber particles. The styrenic resin of the first layer preferably has a glass transition temperature of 120°C or above and the glass transition temperature of the acrylic resin composition of the second layer is usually 120°C or below. It is advantageous to form a three-layered structure wherein the second layers are respectively formed on both sides of the first layer. This resin multilayered film is stretched to obtain the phase difference film. COPYRIGHT: (C)2006,JPO&NCIPI
