Abstract

PURPOSE:To provide the heat sensitive recording material preventing fog phenomenon in the elapse of time and imparting a clear color image comprising containing a colorless leuco dye and a specific alkylene ether derivative in a heat sensitive color forming layer as color forming components. CONSTITUTION:A colorless or a light color leuco dye (A) [e.g.; 3,3-bis(p-dimethylaminophenyl)-phthalide, 3-cyclohexylamino-6-chlorofluorane or the like] and a compound (B) shown by a formula (wherein n is 1-4) (e.g.; bishydroquinone methylene ether, bisresorcine ethylene ether or the like) are contained in a heat sensitive color forming layer slong with, for example, aqueous emulsion type binding agent such as PVA or the like. EFFECT:There are no scum adhesion and sticking to a heat sensitive head and head running property becomes excellent.
