Abstract

A heat-sensitive recording material includes at least a paper substrate, a heat-sensitive recording layer arranged on the front side of the substrate and which has at least one dye precursor and at least one color acceptor, wherein dye precursor and color acceptor react with one another under the action of heat to form color, and an authenticating security feature. The authenticating security feature is a mark which is applied to the back side of the paper substrate and which is made of a tincture having at least one organic solvent. A barrier coating is arranged between the substrate and heat-sensitive recording layer and is suitable to protect the heat-sensitive recording layer against penetration of the tincture into the heat-sensitive recording layer from the back side.
