Thermosensitive recording medium

Abstract

A primary object of the present invention is to provide a thermosensitive recording material that achieves high recording density and excellent preservability of a recorded part, or to provide a thermosensitive recording material that achieves high recording density, and excellent heat resistant and resistance to thermal background fogging property in a high temperature environment, as well as excellent sticking resistance and resistance to dirt adhesion of head. The present invention is a thermosensitive recording material having a thermosensitive recording layer containing at least a leuco dye and a developer on a support; the thermosensitive recording material containing, as the developer, a sulfonamide compound represented by general formula (1); (a) the thermosensitive recording material further having a protective layer on the thermosensitive recording layer; the protective layer containing at least one type of adhesive agent selected from the group consisting of water soluble adhesive agents and water dispersible adhesive agents; and at least one of the thermosensitive recording layer or the protective layer containing a water resistance-imparting agent; or (b) the thermosensitive recording layer further containing saturated fatty acid amide represented by general formula (2).
