Abstract

PURPOSE:To obtain a recording material capable of developing sufficient color concentration at low temperatures in a narrow temperature range from the beginning temperature of coloring by using a specific diphenol compound as a color development agent. CONSTITUTION:A diphenol compound of the formula III as a color development agent is obtained from reaction of an alkenylphenol or its linear dimer of the formula I (where R1 to R3 are each H or an alkyl group) with a mono- or di-substituted phenol of the formula II (R3 and R4 are each H, a halogen, an alkyl, or a cycloalkyl group, but at least one of these is not H) in an acid or alkaline solution. Then, the color development agent and a colorless or light-color chromogenic agent (e.g., crystal violet lactone) are separately dispersed, together with a binder, in a solvent not dissolving both agents to obtain respective dispersions. Then, both the dispersions are mixed, coated on a supporter, and then dried to obtain a recording material.
