PURPOSE:To form a coloring image not susceptible to erasing under an entry image, and improve an effect of preventing alteration partially providing microcapsules including a coloring agent and a mixture layer containing a developer on the surface through printing, and forming a transfer sheet having self-colorability. CONSTITUTION:The pressure sensitive sheet 1 is provided with a transfer sheet 2 having microcapsules including a foaming agent A on the rear surface of a carrier. On the front surface of another carrier, a receiving sheet 8 is provided, having a developer layer 10 that colors in reaction with the foaming agent A. In this instance, in a part of the surface of the transfer sheet 2, there is contained a microcapsule 6 including another coloring agent B, and developer 7. Herein, there is provided a self-coloring area 5 in which at least one of components is supplied by printing. When an entry 12 is done on the surface of the transfer sheet 2 by a ball-point pen or the like writing utensils, the coloring agent B in the self-coloring area 5 reacts to the developer 7, and thereby a coloring image 15 not susceptible to erasing is formed under the entry 12. |
