<p>PURPOSE:To make a center core and an oversheet between which a printing layer is interposed all over the surface hardly releasable and to prevent the generation of whitening at the time of the application of emboss processing. CONSTITUTION:A card 1 is produced by bonding a center core 2 having adhesive layers 3, 4 composed of a pressure-sensitive adhesive provided to both surfaces thereof and also having printing layers 5, 6 applied to all over both surfaces thereof and two oversheets 9, 10 having adhesive layers 7, 8 composed of a pressure-sensitive adhesive provided to one surfaces thereof under predetermined pressure so that the respective adhesive layers 3, 4, 7, 8 are opposed to each other. Since the adhesive layers 3, 4, 7, 8 are provided on both surfaces of the printing layers 5, 6, the center core 2 and the oversheets 9, 10 are certainly bonded and, since no space part is present between the printing layers 5, 6, the center core 2 and the oversheets 9, 10, the card is not whitened even when emboss processing is applied to the card.</p> |
