PURPOSE:To provide a recording material which has an excellent shelf life (chemical resistance) of a non-image part by containing an electron donative achromatic dyestuff, a compound wherein an acyloxyl group is present in a molecule represented by a general formula, and an organic nucleophilic regent. CONSTITUTION:In a recording material, such as a pressure-sensitive sheet and a heat-sensitive transfer sheet, wherein an electron donative achromatic dyestuff and an electron accepting compound are used, an electron donative achromatic dyestuff, a compound wherein an acyloxyl group is present in a molecule represented by a general formula described at the right, and an organic nucleophilic reagent are contained. In the formula, R1 represents -COR3, and R3 represents an alkyl group, an aryl group, an aralkyl group, or an alkoxyl group. Further, R2 is an alkyl group aralkyl group, or -COR3, X is a divalent group, Y is a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, an alkenyl group, or a halogen atom. Further, an oxime derivative and a hydroxamic acid derivative are used as the organic nucleophilic reagent. |
