REVERSIBLE THERMOSENSITIVE RECORDING MEDIUM AND PICTURE RECORDING METHOD

摘要

PROBLEM TO BE SOLVED: To use an OHP(overhead projector) sheet as a document for projection and to make it rewritable. SOLUTION: This recording medium consists of a base layer 2 consisting of a transparent plastic film, a reversible thermosensitive recording layer 4, and a protection layer 5. The recording layer 4 essentially consists of a compound like organic low molecular cholesteric liquid crystal and allows at least visible rays in a partial wavelength range to pass through by quick cooling from a temperature higher than the room temperature after heating to this high temperature and assumes the light scattering state by quick cooling from a temperature higher than the room temperature after heating to this high temperature.
