Abstract

PURPOSE:To obtain a thermal recording material having sufficient developed color density and color forming sensitivity and suitable for high-speed recording, by using a leuco dye, a color developer and, as an auxiliary constituent, a specified nitro compound. CONSTITUTION:A nitro compound of formula I, wherein R is an alkyl, substd. or unsubstd. aryl or aralkyl, is jointly used as an auxiliary constituent, in a thermal recording material utilizing a color forming reaction between a leuco dye and a color developer. At least one leuco dye is used either singly or in combination. For example, a leuco compound of a dye based on triphenylmethane, fluoran, phenothiazine, auramine, spiropyran, indolinophthalide or the like is preferably used. The color developer is preferably an electron- acceptive compound, e.g., a phenolic compound, a thiophenolic compound, a thiourea derivative or an organic acid or a metallic salt thereof. The thermal recording material is produced by applying a coating liquid for forming a thermal color forming layer comprising the above-mentioned constituents to an appropriate base such as a paper, a synthetic paper and a plastic film, followed by drying.
