The present invention aims to provide thermosensitive recording materials
that allow excellent stampability, prevent sticking, represent less
image-density decrease due to image-shielding by protective layers, and
generate less printing residual matters on heads. Specifically, the
present invention provided thermosensitive recording materials that
comprises a protective layer, a thermosensitive recording layer and a
support in this order, wherein the thermosensitive recording layer
develops a color by heating, the protective layer comprises a binder
resin and an inorganic filler, the volume average particle diameter of
the inorganic filler is 0.6 to 5.0 .mu.m, the content of the inorganic
filler is 150 to 400% by mass based on the binder resin, and the
protective layer comprises crosslinked polymethylmethacrylate particles.
