To provide a laser marking multilayer sheet which is excellent in laser marking property, has high contrast between ground color and a printed part, provides a clear letter, mark and image, is excellent in heat melting property in a lamination process, and has sheet conveyance property, release property from a mold after heat press, heat resistance and folding property, in combination.
The laser marking multilayer sheet 1A is formed by laminating a transparent laser marking sheet A and a multilayer sheet B. The transparent laser marking sheet A is a transparent laser marking sheet 3 consisting essentially of a polycarbonate resin. The multilayer sheet B is a multilayer sheet 5 which has skin layers 5a and a core layer 5b, and is formed from at least three layers of laminated sheets, wherein the skin layers 5a as both outermost layers of the multilayer sheet B is formed from copolymerization polyester resin, and the core layer B of the multilayer sheet B consists of a colored multilayer sheet made of polycarbonate resin composition.
