摘要： Provided are an acrylic resin film for a retroreflective sheet having a fluorescent color and a good visibility and a weather resistance, and a retroreflective sheet having a skin material having a fluorescent color and good visibility and weather resistance. An acrylic resin film for a retroreflective sheet of the present invention includes an acrylic resin composition that contains an acrylic resin (A), a fluorescent dye (B), and at least one colorant (C) selected from the group consisting of pigments and dyes (here, a fluorescent dye is excluded), in which a content of the colorant (C) is 1.0 to 4.0 parts by mass with respect to 100 parts by mass of the acrylic resin (A).

摘要： As a laminated film having high transparency, stress whitening resistance, and chemical resistance, a laminated film comprising a layer comprising a fluorine-based resin (X) and a layer comprising an acrylic resin composition (Y), and satisfying the following conditions (1) and (2) is provided. (1) When a test piece is stretched from a chuck-to-chuck distance of 25 mm to 35 mm at a temperature of 0° C. and a tensile rate of 500 mm/min according to ISO 527-3, a difference (ΔW) between a degree of whiteness of the test piece before and that after stretching is 5 or less. (2) The acrylic resin composition (Y) comprises a rubber-containing polymer (B) comprising 30% by mass or more of an elastic polymer (B1).
