Definitions

  • the present invention relates to an assembly, in particular an assembly which is adapted to improve the visibility of an image.
  • the invention also relates to a method for producing an assembly of this type and to the use thereof.
  • indicating signs such as images which are used in the context of aiding safety in the case of emergency situations, for example a fire in a building, which still remain visible for some time even when it suddenly becomes dark, so that they can still fulfil their indicating function. If, for example as a result of the emergency situation, the light goes out, the indication may be adapted in such a manner that it glows for some time as a result of the use of luminescent material.
  • a known product comprising such an indication is formed by sheet material, for example a relatively stiff layer of vinyl, with one side of the sheet material being imprinted with paint or ink which contains an amount of phosphorizing material.
  • Phosphorizing material is a material which, when it has been illuminated, for example using natural light or artificial light, will still glow in the dark for a certain period of time. The glowing of the material is caused by the fact that the electrons in the material which have been excited slowly dropping back.
  • signs are produced on said paint or ink which contains phosphorizing material using dark, usually green (at least non-phosphorizing) ink.
  • the sheet material in some embodiments, is provided with a light, usually white, base.
  • the white base produces an area which is more readily visible than a dark (for example grey, black or green) area.
  • a protective layer (laminate) is provided on top of the phosphorizing layer and the image. This layer protects the combination against outside influences, such as detergents, mechanical influences and/or influences resulting from the incidence of sunlight.
  • the known product has a number of drawbacks.
  • the sheet material is relatively inflexible, so that the material cannot readily be applied to an irregular surface.
  • the assembly of sheet material and protective layer can only be less flexible than the sheet material as such.
  • the sheet material can only be readily applied to a flat surface, which greatly limits the possible uses of the product.
  • the assembly Since both the ink or paint which contains the abovementioned phosphorizing material, and the image itself are applied on top of one of the surfaces of the sheet material, the assembly is relatively susceptible to outside influences. The phosphorizing ink and the image can easily become damaged. This means that both the paint or ink and the image have to be well protected against these influences. However, protection of the assembly requires additional material and effort, such as for example applying one or more protective laminate layers to the assembly.
  • a further drawback is the fact that the production of the product requires a relatively large number of production steps, i.e. applying the paint or ink containing phosphorizing material, applying an image (indicating sign) thereon and finally providing the combination with a protective laminate.
  • Another drawback of the known product is the fact that it has to be made especially for this purpose and that it is not possible to impart the desired glowing properties to an already existing image on any substrate. If, for example, indicating signs on a wall or an image, such as a photograph, drawing and/or text, have been mounted on a poster, it is no longer possible to make them glow in the dark. The indication on the wall or the poster has to be removed first and has to be replaced by a product which has been specially prepared for this purpose. There is a need for an assembly which makes it possible for an existing image on a substrate to glow in the dark.
  • an assembly comprising:
  • the film can be attached to any surface.
  • the surface may in this case already be provided with an image and it is therefore possible to transform any ordinary image into a phosphorizing image.
  • the image may be provided on the side opposite said side to which the adhesive layer is applied, but it is also possible to apply an image first and only then to provide an adhesive layer on top of the image.
  • An assembly of this type may be used in order to improve visibility in the dark of an image on a surface to which the self-adhesive film can be attached.
  • the phosphorizing layer on top of the substrate and the image provided thereon (text, figures, photographs, symbols or the like), the image or, on the contrary, the area around the image can light up in the dark, so that the image remains partly or entirely visible.
  • the assembly in a further embodiment, comprises a removable support, for example a removable covering layer or film.
  • a removable support for example a removable covering layer or film.
  • the removable support is temporarily attached to the film. In this state, the assembly can be readily stored and/or transported. In many cases, the assembly will have been rolled up on a roll, but this is not compulsory.
  • the film is to be used after the storage and transportation stage (i.e. in the operational stage), the removable support is removed.
  • the film, removable support and adhesive layer are in this case configured in such a manner that when they are separated, the adhesive layer is transferred from the removable support onto the transparent film. This means that the film becomes self-adhesive.
  • the transparent film is a calendered monomer film.
  • a thermoplastic is heated to form an extruded sausage-like mass and kneaded and subsequently processed between two or more rollers to form a cooled film of a certain thickness.
  • the resulting film may be the end product, but may also be a semi-finished product. After calendering, the film may be treated further, for example by imprinting it.
  • the thickness of the films is typically between 100 and 500 ⁇ m.
  • the side of the film opposite the side of the adhesive material is adapted to be printed on directly.
  • the adhesive layer in the form of a substantially light, more particularly white, glue layer.
  • the side which is situated opposite the side of the adhesive layer and which is optionally provided with an image is provided with a transparent protective layer.
  • the protective layer is applied after one or more images have been applied on the printable side, for example images which have been printed thereon by means of an ink-jet printer.
  • the transparent film is a polymer cast film.
  • phosphorescent material for example phosphorizing pigment
  • the polymer material is mixed with the polymer material in order to impart the desired phosphorizing properties to the film.
  • very thin films can be produced, typically having a thickness of between 50 and 90 ⁇ m. Due to their low thickness and/or their other material properties, these films are highly flexible and/or extensible. This means that the film can be applied to any surface and therefore also to a relatively irregular surface. It is, for example, possible to apply the film, which is optionally provided with images, onto the paint coat of a vehicle, such as a passenger car or lorry.
  • the film Due to its flexibility, the film can follow the shape of the vehicle entirely. Therefore, when there is sufficient light, it is (virtually) impossible to see that a film has been applied to the vehicle. However, if it suddenly goes dark, for example when the vehicle is driven through a tunnel, the film glows, which produces a special effect.
  • the amount and the composition of the phosphorizing material in the transparent film is chosen such that the transparent film is visible for a period of time in excess of 20 minutes after it has been illuminated with the usual light intensity.
  • the invention also comprises the use of the assembly described herein.
  • a method for producing an assembly comprising:
  • Applying an adhesive layer may in this case comprise the following:
  • the method comprises:
  • the film material may be configured in such a way that image(s) can be applied thereto directly.
  • One or more images can then be applied to the side of the film opposite the side of the adhesive material.
  • the film side can be printed on directly and the method comprises printing images onto the film, for example by means of an ink-jet printer which is known per se.
  • a transparent protective layer is applied in order to protect the image against outside influences, such as scratches, dust, dirt, UV radiation and the like.
  • the protective layer not only ensures that the image is physically protected, but is usually also provided with UV absorbers or stabilizers in order to prevent the colours of the image from fading.
  • the method comprises mixing phosphorescent material and liquid polymer material and casting the liquid mixture in order to produce a cast film.
  • a film may be very thin.
  • the film is highly flexible so that it can also be applied to a surface which has an irregular shape.
  • materials are added to the mixture of polymer material and phosphorizing material which ensure that the film can fulfil the function of the abovementioned protective layer.
  • the film then has properties which are such that the image on the substrate is not only protected against mechanical outside influences (such as scratches), but also against the effects of UV radiation and the like, due to the UV absorbers or stabilizers.
  • Figs. 1a and 1b show a surface (O), for example a wall or floor of a building, onto which an image (A) in the form of an indicating arrow is applied by means of paint, ink or any other means, such as with the aid of a self-adhesive label.
  • the colour of the image is dark, while the area (G) around the image is light.
  • this area is white and the image is green, but different colours or shades of grey are likewise possible, provided the material used (paint, ink, and the like) has sufficient coating power.
  • an embodiment of the assembly according to the invention is applied to the surface and the indicating arrow.
  • Fig. 2 illustrates a first embodiment of the assembly. It shows a thin transparent film 2, on a side 10 of which a layer of glue 4 is provided. On the opposite side 13 of the layer of glue 4, a removable covering layer 3 is provided.
  • the film 2 itself is also transparent or even completely clear.
  • the film is made of a polymer material, for example a cast film, so that the pigment can be mixed in in a more homogeneous manner.
  • the polymer material is firstly made into a liquid in a preparation process.
  • phosphorizing pigments are added to the liquid polymer material.
  • the mixture is then cast onto a casting support and is plastified and dried in the known drying ovens. This is what is referred to as the "cast film” process.
  • the processing of the mixture results in a film having the desired mechanical and optical properties.
  • the film can be made relatively thin, typically in the range from 50 to 90 ⁇ m.
  • the film is highly flexible and can thus be applied to any surface, even when the surface is irregular, for example when the surface is formed by the paint coat on the outside of the body of a motor vehicle.
  • the assembly of film, layer of glue and covering layer is stored and transported on a roll.
  • the covering layer 3 is pulled off the remainder of the assembly by hand. Due to the properties of the covering layer (for example because the covering layer 3 is provided with a siliconed side 13), the adhesive layer 4 will come off the covering layer 3 and only remain attached to the film 2. This situation is illustrated in Fig. 3 .
  • the film 2 has thus become a self-adhesive film which can be applied to a surface.
  • Figs. 4a and 4b show the situation where the film 2 is attached to the surface and the indicating arrow (A) provided thereon by means of the layer of glue 4. Due to the fact that the adhesive layer 4 and the film 2 are transparent, the indicating arrow (A) and the surrounding area (G) are still visible. When the film and the layer of glue are sufficiently transparent, no difference or hardly any difference is noticeable between the surface with and without film when there is sufficient light. However, when the light intensity decreases, for example because the artificial light has been switched off for whatever reason, the film 2 will continue to glow for a certain period of time due to the presence of the phosphorizing material therein.
  • the indicating arrow (A) is dark and the surrounding area (G) is light
  • the surrounding area will now light up clearly in the dark and the area of the indicating arrow remains relatively dark.
  • the indicating arrow is sufficiently visible for a certain period of time, even in the dark. This means that if the lighting in a building fails, for example as a result of an emergency situation, the occupants of the building can still be guided to, for example, an exit of the building by means of the arrow.
  • the film 2 is made from a cast film made from, inter alia, polymer material.
  • This film is so flexible and thin, that the film can be applied on top of an existing surface, without this surface having to be smooth and even.
  • other embodiments are also possible.
  • Such monomer films are generally thicker than the polymer cast films. They are produced by adding an amount of phosphorizing material to the monomer material, mixing these materials and then extruding and subsequently calendering the mixture until a film having the desired properties is achieved.
  • the adhesives or types of glue may preferably be white or opaque and optionally have a composition which is such that they can be transferred from a particular support material, for example silicone paper, to another support material, such as crystal-clear or transparent film. It is also possible to use known crystal-clear or transparent types of glue or adhesives, to which suitable quantities of white pigments or fillers have been added.
  • the monomer film can be used in the same manner as described with reference to Figs. 1a-4b , i.e. as a self-adhesive film which can be applied on top of an existing surface.
  • a monomer film is thicker and less flexible, it is less suitable to be applied to a surface which is irregular.
  • this film has the drawback that it cannot be stuck on top of existing images, since no image would then be visible.
  • the monomer film can also be used in another manner, as is illustrated, for example, in Figs. 5 and 6 .
  • Fig. 5 shows the monomer film 6 which has been provided with a layer of glue 8 and a covering layer or support 17 in the abovementioned manner.
  • the layer of glue 8 is a white or virtually white layer of glue, so that the transparent film 6 is provided with a uniform white background on one side (side 16).
  • the film 6 is provided with an image 9, for example (but obviously not limited thereto), the abovementioned indicating arrow. This image can be applied in a variety of ways.
  • the image 9 can be produced by passing the combination of support 17, film 6 and layer of glue 8 through an ink-jet printer.
  • the invention is not limited to specific types of ink or the number of colours thereof, and it is also possible to use only black ink or ink of one single colour, the invention is in particular suitable for producing colour images, such as the printing of photographs and the like.
  • the base colours yellow, magenta and cyan are usually used, if desired in combination with black ink. Obviously, it is also possible to use a larger number of colours.
  • the ink is allowed to dry first.
  • a film is applied to the side on which the image 9 has been provided, which film is provided with a layer of glue or adhesive.
  • a protective or covering layer 14 is provided on top of the side 15 and the image 9 in order to protect the film and, in particular, the image 9.
  • the covering layer 14 ensures that the image is not exposed to outside influences, such as mechanical influences or the effects of incident sunlight, or at least to a lesser extent.
  • Fig. 5 shows the situation in which the assembly can be placed on a roll for the purposes of storage and/or transportation.
  • the assembly is made available again on a roll, but in other cases, the assembly is stored and/or transported in a different form.
  • the support 17 can be removed again in order to attach the combination to a surface, so that the assembly, that is to say the film 6, image 9 and, if desired, the covering layer 14, becomes self-adhesive.
  • the transparent or, preferably, white layer of glue is configured in such a manner that it remains behind on the surface 16 of the film 6 and comes off the support 17.
  • the assembly is now in the position of use illustrated in Fig. 6 and can be attached to a surface (O) in a known manner.
  • image 9 remains visible when it is light.
  • the film 6 will continue to glow due to the presence of phosphorizing material in the film 6 itself.
  • the entire area of the film will light up more brightly (at least those areas where the white layer of glue is situated) due to the presence of the white layer of glue 8 behind the transparent film 6.
  • the light of the film 6 can then leave the assembly via the covering layer 14.
  • no light will be emitted from certain locations, which means that the image 9 can be identified as a relatively dark area.
  • the image 9 can form, for example, the indicating sign, and as a result the area around the indicating sign lights up in the dark and the area of the indicating sign remains dark.
  • the image 9 in reverse form so that the indicating sign is formed by the area in which the image is not situated. When it gets dark, it will be the indicating sign that lights up and the surrounding area (where the image is not situated) will remain dark.
  • the method of the invention and the resulting self-adhesive film can, for example, be used for all known uses of ink-jet techniques, such as making self-adhesive transparencies of photographs, drawings, graphic designs and the like, for example for use as decoration, logo, lettering and/or for advertising purposes.
  • the surfaces to which the films can be attached can vary and may include vehicles, such as commercial vehicles, racing cars, boats, walls, floors, windows, banners, panels and the like.
