PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic resin sheet for rapidly transferring a precise emboss shape. SOLUTION: In the method for manufacturing a multilayer thermoplastic resin sheet having a central layer 7 and surface layers 6 provided on its surfaces, it is embossed in the state that plasticizer blending amount of the layer 7 is less than that of the layer 6. It is desirable that a glass transition point of the resin of the layer 7 is higher by at least 10 deg.C than that of the layer 6. The plasticizer blending amount of the layer 7 is 0 to 40 pts. with respect to 100 pts. of the resin and the plasticizer blending amount of the layer 6 is 40 to 80 pts. with respect to 100 pts. of the resin. |
