Reversible thermosensitive recording material, and image recording and erasing method using the recording material

摘要

A reversible thermosensitive recording material including: a substrate; a recording layer located overlying the substrate and including a crosslinked resin, an electron donating coloring agent and an electron accepting coloring developer; and a protective layer located overlying the recording layer and including a filler and a crosslinked resin, wherein the recording layer achieves a colored state or a non-colored state when appropriately heating and cooling the recording layer, and wherein the reversible thermosensitive recording material has a surface having at least one of a ten-point mean roughness (Rz) not less than 1.5 mu m or a ratio Sm/Rz not greater than 120, wherein Sm represents an average peak-to-peak length of the surface of the recording material.
