| titleOfInvention | Leuco dye compound and recording material using the same |
| abstract | [PROBLEMS] To provide a leuco dye compound having high color developability, a color dye having a longer wavelength, and having good color fastness, and a recording material using the leuco dye compound. about. A leuco dye compound represented by the following general formula (1) and a recording material using the compound. [Chemical 1] In the formula, R 1 and R 2 each independently represent a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, or an acyl group, and R 3 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, or an acyl group. Represents a group, an alkoxy group, a hydroxy group, an acylamino group or a halogen atom. Ring A represents an aromatic ring or a heterocyclic ring, and Ring B represents a cyclic structure having a function of causing the compound represented by the general formula (1) to develop a color by contacting with an acidic substance. X represents an oxygen atom, a sulfur atom or a nitrogen atom. |
