| titleOfInvention | Method for reversible thermosensitive recording |
| abstract | A method for image forming and erasure is provided that is capable of color formation and erasure which includes a color forming step in which a thermal energy (h1) is given for a short period of time to a recording medium containing a composition containing an amphoteric compound which is a salt or a complex salt of a compound having at least one phenolic hydroxyl group and/or a carboxyl group selected from among compounds represented by the following formula (A) and ester compounds thereof:n n (n is an integer of 1-3); nwith an aliphatic amine selected from among compounds represented by the following general formula (C) or (D) n n n n (C) R₂NH₂ n n n n(where R₂ is an alkyl group having at least 8 carbon atoms)n n (where R₃ is a hydrogen atom, an alkyl group, a halogen atom or an alkoxy group; and n₂ is an integer of 1-18) nto produce a colored image and a step in which thermal energy (h₂) being different from (h₁) is given for a prolonged time to erase said image. |
