Abstract
Abstract A heat-sensitive transferring recording medium comprises a substrate and a solid coating film formed by applying a coating material mainly composed of an emulsion and a coloring agent overlying the substrate. A heat-sensitive transferring recording medium is composed of a substrate, a heat-sensitive releasing layer and a heat-sensitive transferring ink layer laminated in the mentioned order. A heat-sensitive transferring recording medium comprises a substrate, a heat-sensitive releasing layer, a coloring agent layer and a heat-sensitive cohesive layer.
