Title:
REVERSIBLE THERMAL RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP3760431
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a reversible thermal recording medium having small density change at the time of repeated use without notch of the medium even in the case of repeated use with satisfactory color developability and color erasability and to provide a reversible thermal recording medium having small coloring g of a skin by light emission.
SOLUTION: The reversible thermal recording medium comprises a reversible thermal recording layer containing reversible thermal color developing composition for forming a relatively color developed state due to a difference in heating temperatures and/or cooling velocities after heating by using electron donative coloring compound or electron acceptive compound on a support. In this case, the thermal recording layer contains resin of crosslinked state by isocyanate compound.
