ABSTRACT:
A reversible heat-sensitive recording medium has a substrate where a reversible heat-sensitive recording layer and a protective layer are successively formed on top of it. The reversible heat-sensitive recording layer is formed by a reversible heat-sensitive recording material including a leuco dye and a color developing/reducing agent. The color developing/reducing agent is a combination of two kinds of color developing/reducing agents, one with a high color developing ability and the other with high image preservation and stabilization capabilities. The two agents are combined at a ratio between 1:4 to 4:1. Thus a reversible heat-sensitive recording material with a fine color developing ability and high image preservation and stabilization capabilities can be obtained.
