PURPOSE:To provide a reversible heat-sensivie recording material which is capable of performing formation and erasure of an image in a favorable contrast and holding of the image stable with age under circumstances of daily life and superior in sensitivity and repeating durability. CONSTITUTION:In a reversible heat-sensitive recording material containing a dye precursor, which is ordinarily colorless or light-colored, and a reversible developer, which allows the dye precursor to generate a reversible color tone change by a difference in cooling rates after heating, an undercoat layer containing hollow particles is provided between a substrate and reversible heat- sensitive layer. |
