Reversible image recording method using reversible thermosensitive recording material

摘要

A recording method of forming images on a reversible thermosensitive recording material, by bringing a heating element of a thermal head into pressure contact with the reversible thermosensitive recording material, which is capable of assuming a first colored state when heated to a first temperature which is higher than room temperature, and then cooled, and which is capable of assuming a second colored state when heated to a second temperature which is higher than the first temperature, and then cooled, and relatively moving at least one of the heating element or the reversible thermosensitive recording material, wherein the stress exerted on the reversible thermosensitive recording material per unit area thereof, sigma (g/cm2), which is generated by the pressure contact of the heating element with the reversible thermosensitive recording material and the relative movements of the heating material and the reversible thermosensitive recording material, is represented by formula (I): sigma
