Abstract
The present invention relates to a thermosensitive recording material comprising paper, an undercoat layer disposed on the paper, and a thermosensitive recording layer disposed on the undercoat layer, wherein the undercoat layer comprises a binder and first and second hollow sphere polymer particles, wherein the first hollow sphere polymer particles have a diameter in the range of from 1.2 µm to 1.8 µm; the second hollow sphere polymer particles have a diameter in the range of from 0.25 µm to 1.0 µm; the number ratio of the second to the first hollow sphere polymer particles is in the range of from 1:1 to 20:1; the diameter of the second hollow sphere polymer particles is in the range of from 15 to 65% of the diameter of the first hollow sphere polymer particles; the dry bulk density of the first hollow sphere polymer particles is in the range of 0.25 to 0.5 g/mL; and the dry bulk density of the second hollow sphere polymer particles is in the range of 0.30 to 0.90 g/mL.
