Definitions
- the invention relates to a method for producing the cover plate of a neon sign or the like with a carrier plate made of clear, transparent acrylic glass and at least one metal-coated area, in which
- the surface of the carrier plate is provided with a cover layer in the areas not to be coated with metal;
- an embossing foil which has a plastic carrier foil and a metallic layer carried by it, with the metallic layer being pressed onto the heated carrier plate;
- the embossing film is pressed onto this layer structure, its metallic layer remains adhering both to the cover film and to the areas of the carrier plate to be coated with metal. Finally, the cover film is removed so that the metallic coating tion only remains on the desired surface areas of the carrier plate. However, pulling off the carrier film is a relatively complex work step.
- a manufacturing process that eliminates the need to peel off a carrier film is described in DE 42 40 817 AI.
- the carrier plate is coated with an adhesive in the areas to be coated with metal. If the stamping film is pressed onto the carrier plate prepared in this way, the metallic layer of the carrier film only adheres to the areas of the surface of the carrier plate provided with adhesive. When the embossing foil is peeled off, the desired image of the metallic coated area is created directly on the carrier plate. However, it is extremely difficult to find an adhesive which achieves the described effect with the desired reliability and in which a deep-drawing process of the carrier plate can possibly take place subsequently.
- the object of the present invention is to provide a production method of the type mentioned at the outset in which the cover layer no longer has to be removed.
- a highly transparent clear lacquer is used as the covering layer, the glass transition temperature of which is above the softening temperature of the acrylic glass material;
- the layer structure of the carrier plate and clear lacquer is brought to a temperature which is higher than the softening temperature of the acrylic glass material but lower than the glass transition temperature of the clearcoat, so that
- a highly transparent clear lacquer is used as the covering layer according to the invention, it is not necessary to remove this covering layer again; Rather, it can remain in the entire layer structure of the cover plate without disturbing the visual impression.
- the selection between such surface areas that are to be coated with metal and those surface areas in which no metallic coating is to take place is based on the different adhesive properties of these areas: At a suitable temperature, which is between the softening temperature of the acrylic glass material and the glass transition temperature of the clear lacquer only the surface areas to be coated with metal become sticky, but the areas covered with clear lacquer do not. After the stamping foil has been pressed on, its metal layer only adheres to the sticky surface areas formed by the acrylic glass material of the carrier plate, not to the areas coated with clear lacquer, from which it is removed again together with the plastic carrier foil of the stamping foil.
- a UV-curing clear lacquer is preferably used, which therefore hardens and under the influence of UV light does not soften when the temperature is increased.
- cover plates of the type of interest here contain, in addition to the areas to be coated with metal, areas which are to be provided with a colored decoration.
- the decorative dye be applied in the corresponding areas before carrying out steps a to g of the method according to the invention.
- the surface areas of the carrier plate bearing the decorative color, which are not intended to be provided with a metallic layer, are also coated with clear lacquer.
- a particular advantage of the manufacturing method according to the invention is that the finished, coated carrier plate can be subjected to a final deep-drawing process.
- the clear coats used have the required elasticity.
- FIG. 1 schematically the top view of the cover plate of a neon sign produced by the method according to the invention
- Figures 2 to 7 in section along line AA of Figure 1 different stages of the manufacturing process.
- Figure 1 shows a schematic plan view of the cover plate of a neon sign. It comprises a carrier plate 1 made of clear, transparent acrylic glass, which in turn bears a decor.
- a schematic, simple decor was chosen, which consisted of a gold metallic capital letter "T" 2 on a colored, e.g. green, reason 3 and a gold metallic edge 4 is also.
- the cover plate is manufactured in the following way:
- the colored decorative parts are applied by means of screen printing, in the present example the green base 3, on which the "T" 2 is later supposed to be gold-metallic. This is shown in Figure 2.
- the layer thicknesses are shown in an exaggerated manner for reasons of drawing.
- all those areas that are not to be coated with a gold-metallic layer, that is to say in the present example the area of the green base 3, are covered congruently with a layer 5 of highly transparent clear lacquer.
- This clear lacquer is preferably a UV-hardening lacquer whose glass transition temperature (softening temperature) is significantly above the softening temperature of the acrylic material of the carrier plate 1.
- the softening temperature of clearcoat 5 should be above 150 ° C.

Abstract
La fabrication de la plaque de recouvrement d"une enseigne publicitaire lumineuse ou analogue consiste, dans un premier temps, à imprimer d"une peinture décorative une plaque support (1) en verre acrylique clair, transparent, dans les zones où une telle peinture doit être appliquée. Toutes les zones qui ne doivent pas être munies d"une couche métallique sont ensuite recouvertes d"un vernis clair hautement transparent (5). La température de transition vitreuse (température de ramollissement) de ce vernis clair (5) est supérieure à la température de ramollissement du matériau en verre acrylique. La plaque support (1) est ensuite portée à une température supérieure à la température de ramollissement propre, mais toutefois inférieure à la température de transition vitreuse du vernis clair (5). Une feuille grainée (6), comprenant une feuille support en matière plastique (7) et une couche métallique (8) est pressée préalablement, conjointement avec la couche métallique (8), sur la structure stratifiée comprenant la plaque support (1), la peinture décorative (3) et le vernis clair (5). La couche métallique (8) de la feuille grainée (6) reste adhérente aux zones superficielle collantes, exemptes de vernis clair (5), de la plaque support, et non pas aux surfaces non susceptibles de coller dudit vernis clair (5). Après détachement de la feuille grainée (6), la plaque support (1) est ainsi revêtue, exclusivement aux zones voulues, d"une couche métallique (8).
