<p>A laminate film has a coated film layer containing a binder resin and an organic filler. The laminate film satisfies the following expressions (1) and (2) when it is heated at 200 DEG C for 120 minutes: <MATH> <MATH> wherein Ra<1> is an average roughness of root mean square (nm) of an exposed surface of the coated film layer before the heat treatment, and Ra<2> is an average roughness of root mean square (nm) of the exposed surface of the coated film layer after the heat treatment. The film has protrusions with two or more interference fringes on the surface at a density of 100 per 100 cm<2> at the most. The present laminate film is useful as a base film for a magnetic recording medium.</p> |
