The present invention provides an excellent laser marking property, a high contrast between a fabric color and a printed portion, and a clear character, symbol, and image can be obtained, sheet conveyance property, release property from a die after hot pressing, and heat resistance. A transparent laser marking multi-layer sheet that has both flexibility and bendability. A transparent laser marking multilayer sheet 1 formed by co-extrusion comprising at least three layers having a skin layer 3a and a core layer 3b. The skin layer 3a which is both outermost layers of the multilayer sheet is composed of a transparent resin layer mainly composed of a polycarbonate resin, and the core layer 3b is composed of laser light energy with respect to 100 parts by mass of the transparent resin mainly composed of the polycarbonate resin. It consists of a transparent polycarbonate resin composition layer containing 0.0005 to 1 part by weight of an absorbent material, the total thickness of the multilayer sheet is 50 to 300 μm, and the total thickness of the multilayer sheet is the thickness of the core layer 3b. A transparent laser marking multilayer sheet 1 occupying 20 to 80% of the total. [Selection] Figure 1 |
