Abstract
A transparent thermosensitive recording material compriser: (1) transparent substrate, (2) a thermosensitive coloring layer which is formed on one side of the transparent substrate, (3) a protective layer which is formed on the thermosensitive coloring layer and has almost the same refractive index as that of the thermosensitive coloring layer, and (4) an antistatic layer, formed on the protective layer and/or on the backside of the substrate, wherein the surface resistivity and the ten-point mean roughness of the antistatic layer are respectively smaller than 10.sup.10 .OMEGA./.quadrature. and greater than 0.2 .mu.m, and the coefficient of dynamic friction of the backside is greater than 0.2.
