PROBLEM TO BE SOLVED: To more uniformly thermally adhere in a shorter time by incorporating humectant in a thermally adhesive layer and efficiently laminating a thermally adhesive type recording sheet to a postcard by using an electromagnetic heater in the case of laminating them. SOLUTION: As humectant, it is not particularly limited if it absorbs, adsorbs and holds moisture. Specifically, modified starch, acrylic acid derivative or polyethylene glycol compound is used. White pigment of one or more types can be used for an ink receiving layer 1. As the pigment contained as a main body component in the layer, porous inorganic pigment is preferable. Since moisture contains the humectant in a thermally adhesive layer 3 to heat it by electromagnetic wave, the moisture captured to the humectant occupying most of the moisture in the layer 3 is heated. Thus, it can be effectively laminated to a postcard by using an electromagnetic heater. |
