PROBLEM TO BE SOLVED: To provide a shaped film with high emboss transfer rate and further, high emboss heat resistance in the heating process of fabrication. SOLUTION: This shaped film has at least, a face layer formed of a resin, with 100 to 150°C glass transition temperature, composed mainly of a polycarbonate resin. This face layer is subjected to a shaping process and satisfies formula (1) Ra (f2)/Ra (f)= not less than 80%. In this formula (1), Ra (f) is the surface roughness of the shaped film and Ra (f2) is the surface roughness of the shaped film after being retained at 100°C for 60 s. COPYRIGHT: (C)2009,JPO&INPIT
