- second layer covering the first layer FIG. 2
- a different representation of translucent and opaque regions of the second layer (2) is dispensed with.
- the first layer is a mass-dyed web-shaped substrate (11).
- the second layer (2) is applied, for which in principle a range in terms of basis weight between 2 and 10 g / m 2 is considered to be preferred, as very particularly preferred is a range between 4 and 8 g / m 2 .
- a basis weight of the second layer of less than 2 g / m 2
- the coverage of the first layer is often no longer adequately ensured, whereas a second layer with a basis weight of well over 10 g / m 2 for economic reasons does not make sense.
- FIG. 2 shows in this respect, a sheet-like heat-sensitive recording material according to the invention, wherein the recording material is designed in one of its simplest embodiments.
- the second layer (2) whose hollow body pigments are fused by means of the print head of a thermal printer in the form of a typeface, is applied to a substrate (11) formed as a first layer here, for example with carbon black constituents for coloring the substrate.
- the second layer (2) completely covers the subjacent substrate (11).

- the relevant figures are calculated from the "lutro" weight, i. air-dry parts by weight, less the proportion by weight of water in the interior of the pigments as supplied.
- the thus-finished heat-sensitive recording material is fed to a thermal printer.
- the hollow particles of the second layer are melted together with the stearic acid amide and the heat sensitive sensitizer according to a predetermined check pattern by the printhead of the thermal printer so that areas in the second layer with fused components and filled intermediate areas and areas with unfused components and unfilled intermediate areas ent stand.
- the thus prepared recording material thus has a very well recognizable, sharp-edged typeface on with blackened areas where the hollow body pigments are fused together in the second layer by the heat input of the printhead of the thermal printer.
- the blackened areas originate from the uniform color of the intermediate layer, the color of which can be recognized by the transparent areas of the second layer with the hollow body pigments fused there.
- the whiteness of the heat-sensitive recording material according to the invention is determined once with, once without UV, the measurements being carried out in accordance with the specifications of ISO 2469 / ISO 2470, with the proviso that in the measurements made here D65- Light is used at a viewing angle of 8 °.
- the white measurements are carried out using a device of the type Elrepho 3000 (illuminant D 65/10). The values determined are 56% (with UV content) and 52% (without UV), which largely corresponds to a gray paper, but in view of this coating and functional technology this is considered to be acceptable and salable.
- the respective optical print density is determined before and after the formation of a black-and-white checkered thermo-printout with an Atlantek 400 device from Viex (USA) using a thermal head with a resolution of 300 dpi and an energy per unit area of 16 mJ / mm 2 is used.
- the respectively non-printed area or the respective thermo-printed area is measured at three locations with the Gretag MacBeth Densitometer TYPE D19C NB / U densitometer (Gretag MacBeth, 8105 Regensdorf, Switzerland).
- the unprinted areas have a mean optical density of 0.33 ODU (Optical Density Units), for the thermo-printed areas a mean optical density of 1.22 ODU. With a difference of 0.89 ODU as the contrast between printed and unprinted areas, the present invention proves that a skilled typeface is easy to see, underscoring the value of the present invention.
