Coated film and method of laminating the same

A multi-layer application film formed by laminating at least two resin films, a top layer film (I) being formed from a crosslinkable resin coating composition (A), an under layer film (II) being formed from a thermoplastic resin (B), showing practically no stickiness per se, and having a tensile elongation at breakage in the range of 50 to 1000% as a value measured by the use of a sample of 30 mm in length, 10 mm in width and 0.05 mm in thickness under the conditions of a temperature of −10° C. and a stress rate of 200 mm/min., said multi-layer application film being applied onto a plastic substrate.
