Heat-sensitive recording material

A heat-sensitive recording material, comprising:

• a web-shaped substrate, having a front side and a reverse side opposite the front side;
• a heat-sensitive recording layer disposed to the front side of the web-shaped substrate, comprising at least one dye precursor and at least one (color) developer reactive with this at least one dye precursor;
• at least one layer of adhesive applied to the reverse side of the web-shaped substrate;
• a front-side surface of the heat-sensitive recording material that is formed dehesively with respect to the at least one layer of adhesive;
• a furnish disposed above the heat-sensitive recording layer and comprises a silicone component as at least one release agent, wherein the dehesively formed layer is a top surface of the furnish;
• and
• a diffusion layer formed between the furnish and the heat-sensitive recording layer, the diffusion layer being formed by areal diffusion of parts at least of the at least one release agent from the furnish into an upper region, oriented toward the furnish, of the heat-sensitive recording layer applied before application of the furnish,
• wherein a fraction of the at least one release agent of the furnish that diffuses into the upper region of the heat-sensitive recording layer formed being from 5 to 50 wt %.
