摘要：PURPOSE:To enhance developed color density, raw preservability and preservability with time, by constituting a recording material of an electron-donative colorless dye and an electron-acceptive compound consisting of a benzoic acid ester having at least one aromatic hydroxyl group. CONSTITUTION:The recording material is formed from an electron-donative colorless dye such as a triarylmethane compound, a diphenylmethane compound, a xanthene compound and a thiazine compound and an electron-acceptive compound consisting of a benzoic acid ester having at least one aromatic hydroxyl group. Preferred examples of the electron-acceptive compoundinclude the compounds of formulas I , II and III, wherein r is alkyl or aryl, and n is an integer of 1-10, and a specified example thereof is alpha-benzoylethyl 4-hydroxybenzoate.
