A multi-layer film which is excellent in transferability to a metal shape during thermoforming and hardly produces uneven thickness, wrinkles, whitening or cracks on the surface of the obtained molded article. The multi-layer film has a layer (layer A) containing a polycarbonate resin and a polyester-based thermoplastic elastomer and a layer (layer B) containing an acrylic resin, wherein

Multi-layer film, decorative molding film and molded body

A retardation film which has few foreign matter defects and small retardation nonuniformity and meets the required quality of a retardation film is provided with high productivity at a low cost by melt extruding a polycarbonate. The retardation film obtained by stretching and orienting a melt extruded film of a polycarbonate is characterized in that:

Retardation film

A polycarbonate resin film which has an average thickness of 10 to 150 &#x3bc;m, a thickness nonuniformity of 2% or less, a retardation R(589) in the plane of the film measured at a wavelength of 589 nm of 12 nm or less, a retardation Rth(589) in the thickness direction of the film measured at a wavelength of 589 nm of 35 nm or less and is used for optical purposes.
