Abstract
PURPOSE:To ensure sufficient suitability for an optical character reader having a reading wavelength region in an infrared region and ensure that fading is not caused by long-time irradiation with light, by jointly using a compound for generating free radicals when being irradiated with light, in a recording material employing a specified basic dye and a specified p-phenylenediamine derivative. CONSTITUTION:A recording material at least one basic dye selected from compounds of general formulas [I]-[III], at least one p-phenylenediamine derivative selected from compounds of general formula [IV]-[VI], and a compound for generating free radicals when being irradiated with light. In the formulas, each of R1-R6 is hydrogen, a 1-8C alkyl or the like, each of R7-R16 is hydrogen, a halogen or the like, each of R20-R23 is a 1-8C alkyl or the like, each of R27-R34 is hydrogen, a 1-12C alkyl or the like, and each of R43 and R44 is a 1-10C alkyl or the like.
