<p>PROBLEM TO BE SOLVED: To provide a decorative metallic luster film having excellent designing property of a metallic luster tone and tone stability without giving a color difference in a large area, and having excellent molding property.SOLUTION: The decorative metallic luster film comprises a biaxially oriented polyester film including a polyester layer A (denoted by A-layer hereinafter) and a polyester layer B (denoted by B-layer hereinafter) and having 50 or more layers each, alternately laminated in a thickness direction; and the film satisfies all of the following conditions (1) to (6). (1) A polyester resin composition constituting the B-layer contains a residue derived from diol of ethylene glycol and spiroglycol; (2) the polyester resin composition constituting the B-layer contains a residue derived from a dicarboxylic acid of terephthalic acid and cyclohexane dicarboxylic acid; (3) an absolute reflectance of the film is 60% or more in a wavelength range from 400 to 700 nm; (4) a color differenceΔE in a 1000 mm square is less than 2.0; (5) the film shows a stretching stress of 80 N or less at 150°C; and (6) the outermost surface layer is composed of A-layer, and the A-layer as the outermost surface layer has a thickness of 1μm or more and 15μm or less.</p> |
