PURPOSE:To produce a stable copied image without leaving any unrequired recorded image at a transfer layer, by a method wherein at least one compound selected from the group consisting of (a) an organophophorus base compound having a P-OH or P-SH bond and (b) an organic compound having an aminocarboxyl group into a transfer layer and/or a base. CONSTITUTION:An organoiron (III) compound which may be used is selected, for example, from the group consisting of (1) an organophosphorus base compound having a P-OH or P-SH bond (2) a carboxylic acid or dithio-acid and (3) an organic acid such as an organosulfur compound having an S-O bond. In the ordinary paper transfer type pressure-sensitive copying paper, the compound specified above is incorporated into a coated layer of a prepared microcapsule coating liquid and/or into a substrate on which the coating liquid is applied, whereby it is enabled to prevent an unrequired image from being formed in the transfer layer. |
