PROBLEM TO BE SOLVED: To provide a laminated film for metal lamination molding which has excellent molding processability and is excellent in post-retort appearance, gold coloring properties, coloring agent bleed-out resistance and the like. SOLUTION: The laminated film is made by laminating a polyester layer A and a polyester layer B, the polyester layer A comprises a resin composition which consists of 30-70 wt.% of polybutylene terephthalate and 30-70 wt.% of polyethylene terephthalate, and the polyester layer B comprises a colored resin composition which comprises 100 pts.wt. of a resin composition consitsting of 30-70 wt.% of polybutylene terephthalate and 30-70 wt.% of polyethylene terephthalate, and incorporated therewith 0.1-5.0 pts.wt. of a coloring agent, wherein the shortest half-crystallization time of the laminated film is 1-100 s, and an a* value and a b* values measured by a color-difference meter are -30 to 20 and 20 to 70, respectively.
