<P>PROBLEM TO BE SOLVED: To provide a laser marking multilayer sheet which is excellent in a laser marking property, has a high contrast between a material color and a printed part, can provide clear letter, mark and image, is excellent in a heat-fusion property in a lamination process and can satisfy all of sheet conveyance property, release property from a mold after heat press, heat resistance property and folding property. <P>SOLUTION: The transparent laser marking multilayer sheet is made by laminating a multilayer sheet B as an underlayer of a multilayer sheet A. The multilayer sheet A is a transparent laser marking multilayer sheet, wherein skin layers as both uppermost outer layers comprise substantially amorphous aromatic polyester type resin composition and a core layer comprises a polycarbonate type resin composition. The multilayer sheet B is a colored laser marking multilayer sheet, wherein skin layers as both uppermost outer layers comprise substantially amorphous aromatic polyester type resin composition and a core layer comprises a polycarbonate type resin composition. <P>COPYRIGHT: (C)2010,JPO&INPIT |
