Abstract (en)

[origin: EP2329959A1] Heat-sensitive recording material comprises at least one substrate; a heat-sensitive recording layer arranged on the front side of the substrate with at least one dye precursor and at least one color acceptor; a protective layer covering the heat-sensitive recording layer; and a barrier coating containing an ethylene vinyl alcohol copolymer and suited to protect the heat-sensitive recording layer against penetration of chemicals causing uncontrolled desensibilization and color reactions in the heat-sensitive recording layer. Heat-sensitive recording material comprises at least one substrate; a heat-sensitive recording layer arranged on the front side of the substrate with at least one dye precursor and at least one color acceptor, where the dye precursor and color acceptor react with one another under the action of heat to form color; a protective layer covering the heat-sensitive recording layer; and a barrier coating containing an ethylene vinyl alcohol copolymer and suited to protect the heat-sensitive recording layer against penetration of chemicals causing uncontrolled desensibilization and color reactions in the heat-sensitive recording layer, where the barrier coating is disposed between the substrate and the heat-sensitive recording layer.
