A coating replacement film comprising a colored layer, a first adhesive layer, a base film, and a second adhesive layer in this order, the base film comprising a layer A and a layer B, the surface orientation coefficient of the layer B being 0.165-0.180, the difference between the melting point TmB of the layer B and the melting point TmA of the layer A being 20-35 DEG C, and the thickness of the colored layer being 1-10 [mu] m. The residual rate of internal stress (specifically the residual rate of internal stress determined by 1-(Ub/Ua) * 100) in a tensile test at 100 DEG C in either the flow direction or the width direction of the base film is 25% or less.

    一种涂装替代薄膜,其依次包含着色层、第一粘接层、基材薄膜和第二粘接层,前述基材薄膜包含A层和B层,前述B层的面取向系数为0.165以上且0.180以下,前述B层的熔点TmB与前述A层的熔点TmA之差为20℃以上且35℃以下,在前述基材薄膜的流动方向和宽度方向中的任意方向上,100℃条件下的拉伸试验中的内部应力的残留率(具体为通过|1‑(Ub/Ua)|×100而求出的内部应力的残留率)均为25%以下。
