PROBLEM TO BE SOLVED: To provide a double postal card with a double structure and a method of using the same, wherein reply information is sent back covered with a protective sheet formed integrally with the double postalcard. SOLUTION: The double postal card with a double structure in which a sheet of paper comprising three pieces of postcard-size paper made continuous at longer sides is stuck in two plies. The first sheet has a perforated notch formed in one of the continuous parts and a slit notch formed in the other, while the second sheet has a slit notch formed immediately under the perforated notch. On the reverse side of the center piece in the first sheet, a releasing agent layer is formed. The two sheets are stuck together in an unreleasable manner except the center piece. On the center piece in the second sheet, there are successively formed a self color developer layer and a re-releasable/resealable adhesive layer. On the front side of the two pieces across the slit notches in the second sheet, a releasable but unresealable adhesive layer is formed. COPYRIGHT: (C)2009,JPO&INPIT
