Abstract
The present invention provides a thermosensitive recording medium, which is excellent in stamping ability, anti-scratching ability, and water and plasticizer resistance of image area as well as in recording sensitivity, image quality and storage stability. The present invention is a thermosensitive recording medium having a thermosensitive recording layer containing at least a colorless or pale colored basic leuco dye and an electron accepting developing agent as a coating layer on a substrate, wherein at least an outermost layer among the thermosensitive recording layer and other optionally prepared coated layers contains powdered cellulose, wherein the powdered cellulose is prepared by a dry grinding process at ambient temperature. The thermosensitive recording medium preferably contains a condensate composition comprising 2,2'-methylenebis(4-t-butylphenol) as an electron accepting developing agent, and a cross-linked diphenylsulfone compound such as 2,2′-bis[4-(4-hydroxyphenylsulfone) phenoxy]diphenylether as a stabilizer.
