Zusammenfassung:	PURPOSE:To provide the stamping-molded object without the breakage of aggregatcs and the separation of adhesive layers, while organic solvent is not used. CONSTITUTION:A skin material with at most 150kg/cm of stress (at 25 deg.C when 100% stretched) and polypropylene foam are laminated to obtain the laminated layer in which the peel strength of the aqueous adhesive to which aziridine curing agent is added, is reinforced by infrared ray-baking, whereby the composite sheet for stamping mold is obtained.
