摘要： A multi-layer film having excellent surface hardness and transparency, a small heat shrinkage factor and such high brittleness that it is easily trimmed after decorative molding.
The multi-layer film comprises a layer (layer A) which contains a polycarbonate resin having a viscosity average molecular weight of 13,000 or more to less than 20,000 and layers (layer B-1 and layer B-2) which contain an acrylic resin and are formed on both sides of the layer A, respectively, wherein the total thickness of the multi-layer film is 50 to 200 µm, and the thickness of the layer A accounts for 5 to 30 % of the total thickness.
