PURPOSE:To provide a recording material improved in light resistance before using by utilizing the color development of an electron donative colorless dye and an electron acceptive compound. CONSTITUTION:A microcapsule in the recording material contains the electron donative colorless dye expressed by formula I and aniline compound expressed by formula II. In the formula, each of R1-R4 is alkyl group or allyl group, each of R5-R6 is hydrogen atom, alkyl group, alkoxy group or halogen atom, R7-R8 is hydrogen atom or alkyl group, R9 is hydrogen atom, alkyl group, alkoxy group, halogen atom or substituted amino group, R10 is hydrogen atom, alkyl group, alkoxy group, halogen atom, allyl group, allyloxy group, alkoxycarbonyl group, allyloxycarbonyl group, substituted amino group, alkylthio group or allylthio group, (m) is integer 1-4, (n) is integer 1-5. |
