PURPOSE:To prevent the generation of unnecessary developed color contamination on a capsule ink printing part after recording by partially printing the developer layer of a developing sheet with one kind of a capsule ink composition. CONSTITUTION:A developer layer 3 is provided on a support 2 to form a developing sheet and a capsule ink composition 4 containing a color former-including microcapsule and a desensitizing component as fundamental components is partial printed on the coupler layer of the developing sheet. In this case, as the sensitizing agent, any component preventing the reaction of the color former with the developer can be used and, concretely, a quaternary ammonium salt is used and, as the color former, an electron donating color former is used and 3, 3-bis(p-dimethylaminophenyl)-6-dimethylphthalide is designated. As the developer, an electron acceptive developer is used and clays such as acid clay, activated clay, attapulgite, zeolite or bentonite are designated. |
