PROBLEM TO BE SOLVED: To provide a pressure-sensitive copying sheet which is of a non-carbon required type and capable of duplicating confidential information and further, is free from such a trouble that a wax-type transitional fluorescent ink penetrates a base to cause a seepage phenomenon and consequently, a duplication failure occurs, or a strike-through of the ink to the opposite face of the base is generated. SOLUTION: A desensitizing ink layer 7 is formed at least at a part of the surface side of a receptive sheet 2 and the wax-type transitional fluorescent ink layer 5 is formed in a region opposite to the desensitizing ink layer 7 on the back side of the copying sheet 2 through a peelable overprint varnish layer 5. |
