A heat-sensitive recording medium is presented, comprising

Heat-sensitive recording medium and use thereof

A heat-sensitive recording sheet is formed as a laminate and includes at least a first and a second web material. The first web material has a substrate of paper with a watermark and the second web material has at least a substrate and a heat-sensitive recording layer.

Heat-sensitive recording sheet and the use thereof

A method of checking the authenticity of a heat-sensitive recording material having a carrier paper with a recording layer which is arranged on one face and which contains colorant formers and organic colorant acceptors that react with one another when heated; and a security feature provided as a water-soluble dye which fluoresces under UV radiation, the dye being applied without binder in a pattern, invisible under daylight, to a surface of a face of the carrier paper opposite the face provided with the recording layer, so that the entire surface has the pattern, the water-soluble dye being applied at a mass per unit area between 0.01 and 40 mg/m , the method comprising the step of wetting the surface of the layer opposite the recording layer with an alkaline substance.

Heat-sensitive recording materials and method for authenticity checking

A heat-sensitive recording material, comprising a layer support, on whose front face a heat-sensitive recording layer is arranged, containing a colorant precursor and a colorant acceptor which undergoes a colorant formation reaction when it comes into contact with the colorant precursor, an intermediate layer arranged between the layer support and heat-sensitive recording layer, a protective layer that is free from compounds containing silicone, is hardened by actinic radiation and covers the heat-sensitive recording layer and a self-adhesive layer arranged on the back of the layer support, is used as a label material which can be wound on a roll and printed by the offset or flexographic printing process and in which the self-adhesive layer is in contact with the protective layer in the roll.

Use of a heat-sensitive recording material as a label

A heat-sensitive recording sheet has A heat-sensitive recording layer containing color formers and color developers formed on one side of a substrate, a backcoat is formed on the side opposite to the recording layer, wherein this backcoat is formed of A mixture containing starch, an acrylate copolymer which does not comprise styrene or vinyl acetate components and has a film-forming temperature of less than 5&deg; C., and an alkaline catalyst.
