HEAT-SENSITIVE RECORDING BODY

摘要

It is intended to provide an environmentally-friendly heat-sensitive recording body excellent in color-developing sensitivity, water resistance and storage stability (resistance to background color development). The heat-sensitive recording body is provided with a heat-sensitive recording layer containing as main components, a colorless or pale-colored basic colorless dye and a developer which develops a color by reacting with the basic colorless dye on a support, and is characterized in that the heat-sensitive recording layer contains a carboxyl group-containing resin, an epichlorohydrin resin and a polyamine/amide resin. This heat-sensitive recording body is suitable for the usage in which printing is performed with a low applied energy.
