Description

A sheet for displaying information, a process for producing and a use of said sheet
The invention concerns a sheet for displaying information, said sheet comprising at least a surface layer and at least a second layer, where the surface face layer is bonded to the second layer, and where the second layer is at least partly provided with information. The invention further concerns a process for producing and a use of said sheet.
A very important aspect when displaying advertisements is to maintain the advertisements in a flawless state throughout their lifespan because the desired promotion effect may otherwise turn to have the opposite effect. Due to problems of this nature, "horizontal marketing" has been avoided except for a limited use, which has been in-doors and in places with a low wear or where the advertisement is only displayed in a short period. The latter is known e.g. from indoor handball arenas.
"WO 94/08328 describes an advertising device, which is adhered to the floor of a supermarket aisle to promote sales. The device consists of a printed advertisement encapsulated in a layered structure, where the upper layer is transparent or translucent. A solution is disclosed in that the device may consist of a number of printed layers, which may be peeled off one at a time to reveal a new layer. This leads however to several problems, e.g. the need for surveillance and how to decide when to expose a new layer. Another problem involved is the thickness, which constitutes an obstacle. People could trip and physically challenged people may have difficulties with wheelchairs etc. A further problem is that the known devices become very slippery when they are wet. Therefore spilled soft drinks etc. as well as when the floor is recently washed, propose a serious risk. One aspect of the invention is to provide a sheet for "horizontal marketing", which is wear resistant such that it may be used for extensive periods of time, not only outdoors, but also in places with heavy traffic, without hiding, or blurring the marketing information. Another aspect is to provide a sheet for "horizontal marketing", which according to the concerned technical standards is sufficiently non-skid to be used in traffic paths, such as public roads etc. A further aspect is to provide a sheet for "horizontal marketing" according to the mentioned aspects and at the same time has a thickness of less than 2 mm, such that vehicles passing do not perceive the sheet as an obstacle or inconvenience.
The new and inventive features of the present invention involve that the second layer comprises an elastomeric material and that the surface layer com- prises a transparent, wear resistant plastic material, where the surface layer on its free surface is provided with a distributed amount of partly embedded anti-skid particles and/or glass beads, such as e.g. balls of transparent glass and crushed transparent glass.
Hereby several technical effects are obtained in that the second layer is flexible and elastic, whereby it may yield to loads from vehicles etc., whereby the load(s) are distributed and transmitted to the underlying surface instead of being concentrated in a way, which would otherwise have been destructive. Also, the elastomeric material is characteristic in the sense that it can withstand very large strains and remain elastic. The surface layer is also flexible in order to distribute rather than concentrate loads, but the main thing is that it may comprise the combination of transparency and large wear resistance, both important features for displaying the information and for the continuation of the display without getting worn in a way, which blurs or dims the clarity of the displayed information. Crushed transparent glass makes the surface non-skid under all conditions, even in rainy weather, and remains transparent when subjected to wear. The anti-skid particles and/or glass beads, e.g. balls of transparent glass, have an effect relating to the non-skid properties and a considerably large effect with regard to wear resistance.
In one embodiment, the thickness of the second layer may be between 0,4 mm and 1 ,2 mm. "Within this interval, the total thickness will be suitable, without getting too thick, and the flexibility of the second layer be adequate for adapting to even a large unevenness of the underlying road, pavement etc.
In one embodiment, the thickness of the surface layer may be between 0,050 mm and 0,250 mm, thereby sufficiently thin to clearly expose the underlying information and appropriately thick lo obtain the necessary wear resistance. In one embodiment, the size of the balls of transparent glass may be mainly between 0,1 mm and 1,5 mm, preferably between 0,2 mm and 1,5 mm, and most preferably between 0,4 mm and 0,8 mm. If the balls are larger, they obtain an unwanted optical effect, which blurs the information, and if they are smaller, they cannot provide the load-carrying level, which is raised slightly from the surface layer.
In one embodiment, the size of the crushed transparent glass may be mainly between 0,1 mm and 1,0 mm, preferably between 0,2 mm and 1,0 mm, and most preferably between 0,4 mm and 0,8 mm. If the size is smaller, the non-skid effect largely disappears, whereas if the size is larger, the sharp edges can present a risk of cutting to people accidentally falling or to e.g. the paws of dogs and cats etc.
In one embodiment, the amount of balls of transparent glass is between 15 g/m2 and 250 g/m2, preferably between 50 g/m2 and 250 g/m2, and most preferably between 150 g/m2 and 200 g/m2. If the amount is smaller, the load-carrying wear level, which is raised slightly from the surface layer, will not be established. If the amount is higher, the balls start blurring the display of the information.
In one embodiment, the amount of crushed transparent glass is between 1 g/m2 and 250 g/m2, preferably between 15 g/m2 and 100 g/m2, and most preferably between 20 g/m2 and 50 g/m2. If the amount is smaller, the non-skid effect is too small and the surface may be slippery, especially when wet. If the amount is higher, the small sharp edges, which are reflecting and refracting light, start blurring the display of the information.
The sheet may further comprise a fibre-reinforced layer. This may be used to increase the strength of the sheet, as well as the in plane stiffness, which may be desired when making very large sheets, in order that the information is not dis- torted.
The sheet may also comprise a layer of flexible sheet material, such as a layer of fabric or cloth, or a layer of nonwoven fabric or bonded-fibre fabric. This layer is preferably applied to or partly embedded in the second layer at the surface opposite the free surface of the surface layer. Such a layer provides for increased sta- bility to the sheet, in particular in the sense that it prevents the elastomeric material from sinking into the underlying surface when the sheet is subjected to extreme loads. The sheet may on the side opposite the free surface of the surface layer be provided with a layer of glue. This ensures a very easy way of mounting the sheet.
The layer of glue may be provided with a release foil, e.g. a polymeric foil, protecting the layer of glue. Thereby, the layer of glue is protected during storage and transport, and may be exposed just before or during installation.
In one embodiment, the surface layer primarily comprises polyure- thane, which material combines elastic properties with transparency as well as a high wear resistance.
The process of producing the sheets may at least comprise the steps of: a) Dispensing the second layer from a coil; b) Printing, e.g. by digital printing, of information on the second layer; c) Applying the surface layer in a fluent state to the second layer; d) Partly embedding anti-skid particles and/or glass beads, e.g. balls of transparent glass and crushed transparent glass, to the surface layer while this is at least partly uncured; e) Curing of at least the surface layer, preferably at an elevated temperature; and f) Cutting sheets to suitable sizes and shapes
The sheets may be used preferably for outdoor advertising. This may involve any aspect of advertising, such as announcements, text, images, pictures, graphical images, symbols, logos, trademarks, colours, shapes etc.
The sheets are preferably placed on driveways, walkways, pavements and the like.
Also, two or more sheets may be placed together to commonly form and display information. This provides a suitable way or establishing very large announcements or the like.
The sheets may also be placed vertically on building walls, billboards and the like. Also, the sheets may be used in combination with light or sound emitting equipment, e.g. lasers creating effects due to the reflecting nature of the balls of glass.
