RECORDING MEDIUM FOR RECORDOR

PURPOSE:To obtain a mono-sheet type recording medium and two kinds of recording media for normal paper recording by using a permeable film that coloring precursors contained in microcapsules penetrates as a base material which is coated with microcapsules. CONSTITUTION:The slightly acid paper D that the coloring precursors a1, a2, a3 which color in an acid atmosphere is used as the base material of the recording medium and one surface is coated with microcapsules A. The color precursors a1, a2, and a3 are inactivated when irradiated with an electromagnetic beam. Then microcapsules A which are not inactivated are pressed and broken through a pressure developing device 15 and precursors a1, a2 and a3 pressed out of the microcapsules are oxidized with additives of the weakly acid paper to color, thereby forming an image on the opposite side from the surface coated with the microcapsules A. A recording medium 3 for recording on general paper for printing which is coated with neither a sensing agent F nor a color developer is coated with a color developer F and heating fusible resin H for making the precursors a1, a2, a3 color on the opposite surface from the surface coated with the microcapsules A.
