Definitions
- the invention relates to an optically encodable, sheet-like material with a base for 5 bodies provided at least on one side with a thermal layer.
- Thermally inscribable materials are usually understood to mean papers provided with a thermal layer. These papers are processed in thermal printers which, by briefly heating the thermal layer, produce a color change and thus fonts or graphics. Advantages of thermal labeling are, above all, the low noise and the high printing speed in the representation of graphically designed prints.
- thermal lettering Disadvantages of thermal lettering are in particular the low light fastness and the chemical sensitivity of the lettering produced.
- this cover layer consists of polyvinyl alcohol, which is also usually used when the thermal
- thermoreactive substances 20 layer is used as a binder for the thermoreactive substances.
- the invention was therefore based on the object of improving the light-fastness and the chemical resistance of the thermal coating in the case of a material of the type mentioned at the outset. According to the invention, this is achieved in that the thermal layer is covered with a UV lacquer (acrylic polymer) as a protective layer.
- a UV lacquer acrylic polymer
- UV lacquers harden without generating heat by being subjected to UV radiation.
- the top layer made of UV varnish offers excellent protection against chemical stress and has high temperature resistance, which property is particularly important for the labeling process.
- the cover layer consists of at least two thin films.
- the film adjacent to the thermal layer can be optimized with regard to good adhesion and chemical compatibility with the thermal layer, while the film facing the surface to be labeled or the thermal printer with regard to chemical resistance, heat resistance and the others from the thermal print head related properties can be optimized.
- the outer film of the protective layer can contain a lubricant.
- a silicone oil or silicone resin is particularly suitable in an amount of 1% to 10% of the film weight.
- the base body is preferably formed at least partially from a plastic, in particular from a PVC film.
- a plastic in particular from a PVC film.
- the thermal layer can contain a UV lacquer (acrylic polymer) as a binder,
- the UV varnish is applied to the thermal layer in high pressure, in particular in direct or indirect letterpress printing, and cured by UV radiation.
- a first film in the form of a paste-like UV lacquer with a basis weight of 1 to 5 g / m 2 is advantageously applied.
- a second film is applied to said first film by weight an offset with a lubricant UV-paint with amoverss ⁇ of '2 to 5 g / m z is applied and cured under UV irradiation excluded.
- This second film is preferably applied only selectively to parts of the surface.
- the optically encodable material uses a homogeneous PVC film as the base body 1.
- Other materials can also be used for this, for example films made of polyester, polyethylene or tear-resistant or synthetic papers.
- the thermal layer 3 On one side of this base body, which was applied in a coating process with subsequent air drying.
- the thermal layer generally consists of a waterproof binder in which thermoreactive substances are embedded.
- a protective layer is applied to the thermal layer 3. This is
- Protective layer consists of two thin films 4 and 5.
- the film 4 lying directly on the thermal layer is advantageously applied over the entire area with an offset printing machine and cured by UV radiation. Since the time between application and curing is relatively short (fractions of a second) there is practically no impairment of the thermal layer.
- the UV lacquer is applied in a viscous or paste-like form in order to prevent penetration into the thermal layer.
- the order quantities are advantageously between one and five grams per square meter.
- a second film 5 is then applied to this first film 4 of the protective layer, which in turn consists of a UV lacquer.
- This varnish for the second film 5 contains 1% to 5% silicone oil or silicone resin in order to achieve a water-repellent effect and to improve the sliding properties of the thermal print head.
- the second film 5 of the protective layer can be selectively applied to the surface in order, for example, to specifically create surfaces which can be inscribed with ballpoint pens, pencils or the like, in that these surfaces are not included the second
- Film 5 can be coated.
- the UV varnishes are usually applied transparently. However, transparent coloring is also possible.
- optically encodable material is to be printed in color, for example, the printing colors between the first film 4 and. applied the second film 5 of the protective layer.
- Such a material can be easily labeled or labeled with conventional thermal printers.
- the thermally generated inscription is very stable and insensitive to oils, fats and solvents (for example alcohol or acetone).
- the light fastness is also significantly improved.
