A thermosensitive recording material having at least a thermosensitive recording layer on one surface of a support and a back coat layer on the other surface of the support, wherein the black coat layer includes multiple layers, and an outermost layer of the back coat layer furthest from the support contains polyvinyl alcohol, an inorganic stratiform compound, and an inorganic pigment. According to the thermosensitive recording material curling caused by a change in environment or by application of heat during recording can be prevented and a coefficient of friction of a back coat layer can be regulated to within a predetermined range.

Thermosensitive recording material

The present invention provides a high-quality heat-sensitive recording material which can prevent curling attributed to an environmental change or heating during recording, is free of deformation of the material, and is applicable to a wide variety of fields. The heat-sensitive recording material of the present invention has at least a heat-sensitive recording layer on one side of a support and a back coat layer on the other side, wherein the back coat layer comprises a plurality of layers, and the outermost layer in the back coat layer most remote from the support contains an inorganic lamellar compound and/or polyvinyl alcohol. The inorganic lamellar compound is preferably water-swelling synthetic mica.
