PURPOSE:To prepare multicolor pressure-sensitive paper efficiently by printing ink including a substance, which displays desensitizing properties peculiarly strongly to one kind of electron donative coloring agents but does not display desensitizing properties at all to another one kind or displays only weak desensitizing properties, to one position or more of partial sections on an electron acceptable developer containing layer. CONSTITUTION:A CB layer is formed by using microcapsules including two kinds or more of coloring agents, desensitizing manners of which differ. A substance, which indicates desensitizing properties to at least one kind of the coloring agents peculiarly strongly but does not designate desensitizing properties at all to at least one kind or displays only weak desensitizing properties, is printed to one part on an electron acceptable developer layer (a CF layer). Since at least one kind of the coloring agents employed does not color or is difficult to color at the position of printing of the desensitizing substance, the coloring of a color tone different from a non-printing section is displayed, and the color tones of two colors are obtained. Two kinds or more of desensitizing substance containing ink are printed at different places on a developer containing layer, thus also manufacturing multicolor copying pressure- sensitive paper. |
