PURPOSE:To obtain the titled sheet capable of transferring inexpensively in a resource-saving manner on plain paper, by coating a base sheet with an alcoholic flexographic ink made of a color former-containing microcapsule and a color developer-containing microcapsules. CONSTITUTION:A flexographic ink is prepared by blending an electron-donating organic color former (A) (e.g., rhodamine-B-anilinolactam)-containing microcapsule, an electron-accepting organic color developer (B) (preferably p-phenylphenol/formalin resin)-containing microcapsule, a binder (C) (e.g., polyvinyl acetate), and a solvent (D) mainly consisting of low boiling point 1-3C alcohol (e.g., methyl alcohol). Then, a base sheet is coated with this ink to obtain a purpose sheet. The microcapsules are preferably pulverized finely before use. EFFECT:It has an excellent long-term preservation stability, and its color formability is hardly decreased. |
