Definitions
- the present invention relates to display films self-adhesive comprising at least one loaded layer electrically, which are suitable for adhering automatically on most smooth surfaces such as windows, walls, paintings or the like.
- the invention relates to especially those that include at least one first dielectric layer, said layer comprising a part, a first side, and secondly, a second side electrically charged.
- Display films of this kind which are known at present, usually include a layer that is made of polymer, preferably polypropylene. Due to the electrostatic force generated by the presence of electrical charges that are contained in inside this layer it is possible to do instantly adhere to the display movies on most smooth surfaces.
- the present invention is intended in particular to remedy these disadvantages.
- the display films of the kind in question are characterized in that a first screen layer, which is adapted to barrier the electric field, is fixed on at least said first face of the first dielectric layer, and this the first screen layer (3) consists of a material which has a conductivity value of at least 10 -10 S / cm.
- Layers 2 and 3 form a self-adhesive film 6 adapted to adhere automatically to smooth surfaces, while layers 4 and 5 form a sheet protective cover 7 removable.
- the material of the dielectric layer 2 is a plastic material, preferably polypropylene, which presents the property of preserving particularly well the electric charges.
- Other materials can also be used, such as for example polyethylene terephthalate (in particular sold under the trademark Mylar by Du Pont de Nemours), polytetrafluoroethylene and polyfluoroéthylènepropylène.
- Layer 2 has a thickness whose value is, for example, between 1 and 100 ⁇ m.
- the material of layer 3 preferably has a minimum conductivity value of 10 -10 S / cm. It is particularly adapted to barrier the electrostatic field due to the electrical charges contained in the layer 2.
- the material chosen for layer 3 is conductive preference, transparent or not. It could be metal, especially aluminum, but can also be consisting of a conductive polymer, a metal oxide transparent and conductive, a conductive ink, or others.
- Layer 3 has a thickness whose value is, for example, between 10 ⁇ and 10 ⁇ m.
- the layer 3 is fixed on the layer 2 for example by bonding, by vacuum deposition metallization, by coextrusion, a conductive lacquer or others.
- the visible side of layer 3 is intended to be printed by a conventional printing process, for example offset type, silk screen, digital, laser, jet ink, typographic, heliographic, or others.
- the visible face of the layer 3 may, prior to this impression, receive a specific treatment intended to favor the maintenance of inks, for example by ionic or electronic bombardment, or by deposit or coating of an underlayer hooking.
- a additional layer 8 that can be printed (Figure 2) can be fixed on the visible side of the layer screen 3, in which case it is this extra layer and not the layer 3 that is printed.
- This extra layer consists of a flexible material with characteristics favorable to printing, especially in terms of visual appearance, color, opacity, grain, etc. .... material may be, for example, ink, paper, polyester, polyethylene, polypropylene, or the like.
- Layer 8 could also be a layer of material on which one can write by means of a felt erasable, the writing thus made on layer 8 being erasable by simply wiping dry.
- the material used for layer 4 is a plastic any, for example polypropylene, polyethylene terephthalate (in particular sold under the trademark Mylar Pont de Nemours), polyester, PVC or polyethylene.
- layer 4 is preferably made of the same material as that of the layer 2 and advantageously has a thickness substantially identical to that of layer 2.
- Layer 5 on the other hand, consists of a electrically conductive material, for example the same than that of the screen layer 3.
- the layer 4 and the layer 5 can be fixed one to each other respectively in the same way as layer 2 and layer 3.
- electrical charges are deposited in the material and on the face of layer 2 which is intended to come into contact with layer 4. These charges are deposited by a process classic, such as for example the Corona effect, the ion bombardment or electron bombardment. of the means are then provided so that during this operation, layer 3 can be electrically connected to a potential predetermined, for example that of the earth.
- This support also presents the possibility of being taken off in order to be repositioned, for example on a other flat surface.
- the display medium according to the invention is covered temporarily by the protective sheet 7 which is consisting of all layers 4 and 5.
- the protective sheet 7 adheres spontaneously on layer 2.
- Layers 2 and 4 are then held together by the force of attraction electrostatic generated by the presence of charges in layer 2, the latter do not able to escape from the display medium thanks to the good insulating and material retention properties of the material two layers 2 and 4.
- Such an arrangement of the layers 3 and 5 has for advantage of canceling the external electric field which without they, would be created by the electrical charges present in layer 2.
- the display medium according to the invention can be conditioned in reams. This one can therefore without problem be sheet-fed in a press or printer, the various supports that constitute a train that does not risk not to stick to each other at the time of the impression.
- the layer 4 is itself electrically charged with a charge opposite to that of the layer 2.
- the self-adhesive film 6 and the set consisting of layers 4 and 5 may be used separately as self-adhesive display films.
- means may be be provided for electrically connecting layers 3 and 5 between them, which has the effect of improving the retention electrical charges in layer 2 and to facilitate the cancellation of the external electrostatic field.
- the self-adhesive film 6 can then be applied by its layer 2 on any smooth surface, after removing the protective sheet 7.
- the material chosen for layer 2 is a transparent material such as for example polypropylene
- the layer 3 is itself made of a material transparent and conductive such as a metal oxide transparent, for example an indium and / or tin oxide, polyaniline, or a compound of polyaniline and polymetracrilate, or a compound of polyaniline and polycarbonate, so as to be able to display and view the display medium on and at through a transparent surface (glass) on which would affixed the dielectric layer 2 of the film 6.
- the self-adhesive film 6 and the protective sheet 7 are bonded together by one of their edges.
- This link facilitates the passage of display film according to the invention in certain machines printing with rollers for example. So, the self-adhesive film 6 and the protective sheet 7 do not risk not to shift when passing between rollers, if the edge on which they are linked goes first between these rollers.
- This connection can be made by heat-sealing over a width of about 1.5 cm. In that case, this band is advantageously cut after printing the self-adhesive film 6.
- this connection can be ensured by a sticky tape or any other means of this type.
- the display medium could possibly be constituted by the self-adhesive film 6 alone, without the protective sheet 7, in which case the layer 3 already avoids in itself the accumulation of dust on the printed side of the display medium.
