Decorative film with cover film and method for manufacturing same and method for mounting same

A method for manufacturing a decorative film with a cover film, comprising:

• (a) providing a base layer having a first surface and a second surface opposite to the first surface;
• (b) forming a polyurethane layer on the first surface of the base layer, the polyurethane layer having a first surface and a second surface opposite to the first surface and containing a polyurethane that is crosslinked at least partially, wherein the polyurethane that is crosslinked at least partially includes at least one of a polyester-based polyurethane or a polycarbonate-based polyurethane, and the first surface of the base layer is in contact with the second surface of the polyurethane layer;
• (c) providing a removable cover film;
• (d) treating a surface of the removable cover film with corona or plasma;
• (e) laminating the removable cover film over the polyurethane layer such that the corona treated or plasma treated surface of the removable cover film contacts the first surface of the polyurethane layer;
• and
• (f) forming an adhesive layer on the second surface of the base layer to obtain a decorative film with a cover film.
