ABSTRACT:
A thermosensitive recording sheet comprising a support material; a primer layer formed on support material, comprising a filler and a binder agent; a thermosensitive coloring layer formed on the primer layer, comprising a colorless or light-colored leuco dye, and an acidic material which colors the leuco dye upon application of heat thereto; and a protective layer formed on the thermosensitive coloring layer, comprising a water-soluble polymeric binder agent and a filler. This thermosensitive recording sheet has high dynamic thermal coloring sensitivity and is capable of yielding sharp images with high image density at low energy consumption with good thermal-head-matching properties such that materials are not generated which come out of the thermosensitive recording layer and adhere to the thermal pen or head during the recording process, thereby causing the thermal pen or head to stick to the thermosensitive recording sheet.
