Abstract: A thermosensitive recording medium includes a base material; a thermosensitive recording layer; and an under layer disposed between the base material and the thermosensitive recording layer and containing a non-thermally-expandable hollow filler. The thermosensitive recording medium includes a hydrocarbon, where an amount of the hydrocarbon having from 3 through 16 carbon atoms is 0.2 mg/m2 or more, relative to an area of the thermosensitive recording medium.

Abstract: Provided is a thermosensitive recording medium including: a transparent base material; a thermosensitive recording layer over the transparent base material; and a barrier layer over the thermosensitive recording layer, wherein the barrier layer contains hollow particles and a binder resin, and wherein when thermal energy is applied to the thermosensitive recording layer from a surface of the thermosensitive recording layer having the transparent base material, the thermosensitive recording layer develops a color. Also provided is a thermosensitive recording medium producing method including: a step of forming a thermosensitive recording layer over a transparent base material; and a step of forming a barrier layer containing hollow particles and a binder resin over the thermosensitive recording layer.

Abstract: Provided is a thermosensitive recording medium including: a transparent support; a thermosensitive recording layer provided over the transparent support; and a protective layer provided over the thermosensitive recording layer, wherein the protective layer contains an ultraviolet-ray-curable resin and a pigment other than silicone resin pigments, and wherein a maximum height Rz of a surface of the protective layer is 0.2 micrometers or greater but 1.0 micrometer or less.
