Zusammenfassung:PROBLEM TO BE SOLVED: To provide an acrylic resin film which has excellent resistance to bend-whitening, a reduced number of projections such as fish-eye defects on a film surface, and thereby, improved surface properties without degrading characteristics of an acrylic resin film, which prevents printing omission, and which exhibits improved film thickness accuracy of the film and improved color irregularity when a colorant is compounded.SOLUTION: An acrylic resin film comprises a multilayer structure acrylic resin including a rubber elastic layer formed by a melt-extrusion method. The film has a film thickness of 30 to 300 μm. When the film is divided into segments each having a width of 3 cm, a film thickness difference between adjoining segments is 1% or less of an average film thickness; and film thickness accuracy in 1 mis 3% or less. 【課題】アクリル系樹脂フィルムの特徴を損なわず、耐折曲白化性に優れ、フィッシュアイ等のフィルムの表面の凸部を減少させて表面性を改良し、印刷抜けを起こさず、かつフィルムの膜厚精度を向上させ、着色剤配合時の色ムラを改善する。【解決手段】ゴム弾性体層を含む多層構造アクリル系樹脂を溶融押出法により成形したアクリル系樹脂フィルムであって、フィルム厚みが30〜300μmであり、フィルムを3cmの幅で区分した時に隣り合う区分の膜厚差が平均膜厚の1%以下かつ1m2中の膜厚精度が3%以下であるアクリル系樹脂フィルム。【選択図】なし
