A thermosensitive recording material, comprising: a support; an under layer; a thermosensitive recording layer; and a protective layer, where the under layer, the thermosensitive recording layer, and the protective layer are provided in this order on at least one surface of the support, wherein the support is synthetic paper, or a synthetic resin film, and wherein the under layer contains a binder resin and hollow particles, characterized in that the binder resin comprises an acrylic resin containing a carboxyl group and a polyvinyl alcohol containing a carboxyl group, the hollow particles are nonfoamable hollow particles, each of which is composed of a shell of a thermoplastic resin, and air or another gas contained therein, and is already in the foamed state, the thermosensitive recording layer contains a leuco dye, color developer and a binder resin, and an adhesive force of the thermosensitive recording material at -20°C is 10.0 N/25 mm or greater, where the adhesive force is measured by cutting out the thermosensitive recording material into a sample having a width of 25 mm and a length of 30 cm, bonding one end of an outermost surface of the sample at the side of the thermosensitive recording layer above the support to a substrate by 8 cm in an environment of 22°C and 50%RH, leaving the sample to stand in an environment of -20°C to adjust temperature of the sample to -20°C, pulling the other end of the sample in a 180 degrees direction with respect to the substrate, measuring a force (N/25 mm) at which the sample is peeled from the substrate by means of a digital force gauge, and determining a maximum value of the measured force at -20°C as the adhesive force. a support; an under layer; a thermosensitive recording layer; and a protective layer, where the under layer, the thermosensitive recording layer, and the protective layer are provided in this order on at least one surface of the support, wherein the support is synthetic paper, or a synthetic resin film, and wherein the under layer contains a binder resin and hollow particles, characterized in that the binder resin comprises an acrylic resin containing a carboxyl group and a polyvinyl alcohol containing a carboxyl group, the hollow particles are nonfoamable hollow particles, each of which is composed of a shell of a thermoplastic resin, and air or another gas contained therein, and is already in the foamed state, the thermosensitive recording layer contains a leuco dye, color developer and a binder resin, and an adhesive force of the thermosensitive recording material at -20°C is 10.0 N/25 mm or greater, where the adhesive force is measured by cutting out the thermosensitive recording material into a sample having a width of 25 mm and a length of 30 cm, bonding one end of an outermost surface of the sample at the side of the thermosensitive recording layer above the support to a substrate by 8 cm in an environment of 22°C and 50%RH, leaving the sample to stand in an environment of -20°C to adjust temperature of the sample to -20°C, pulling the other end of the sample in a 180 degrees direction with respect to the substrate, measuring a force (N/25 mm) at which the sample is peeled from the substrate by means of a digital force gauge, and determining a maximum value of the measured force at -20°C as the adhesive force.
