Abstract
A method of producing a reversible thermosensitive recording material composed of a support, and a reversible thermosensitive recording layer formed thereon, which contains a matrix resin and an organic low-molecular weight material dispersed in the matrix resin, and capable of reversibly assuming a transparent state and a white opaque state depending upon the temperature thereof, is composed of the steps of applying a solution or dispersion of the matrix resin and the organic low-molecular-weight material dissolved or dispersed in a solvent to the support, and drying the applied solution or dispersion with the application of heat thereto in such a manner that when the temperature of the solution or dispersion applied side of the support it t.sub.1, and the temperature of the back side surface of the support, opposite to the solution or dispersion applied side thereof, is t.sub.2, t.sub.1 is lower than t.sub.2 (t.sub.1 <t.sub.2), with the back side surface of the support being heated immediately after the coating of the solution or dispersion.
