PROBLEM TO BE SOLVED: To provide a multilayer acrylic resin film excellent in heating whitening resistance. SOLUTION: In the multilayer acrylic resin film, at least one side of a layer (A) containing 75-90 wt.% of a methacrylic resin and 10-25 wt.% of an acrylic rubber particles on the basis of total 100 wt.% of the methacrylic resin and the acrylic rubber particles is overlaid with a layer (B) containing 90-100 wt.% of the methacrylic resin and 0-10 wt.% of the acrylic rubber particles on the basis of total 100 wt.% of the methacrylic resin and the acrylic rubber particles. The acrylic rubber particle is a multilayer elastic polymer particle having a polymer described in the specification, the layer of an elastic polymer described in the specification which is formed on the outside of the polymer, and an average particle size of 100-400 nm. The thickness of the whole film is 20-300 μm, and the thickness of the layer (B) is 50% or below of the thickness of the whole film and at least 5 μm. COPYRIGHT: (C)2010,JPO&INPIT
