Abstract
A metallised film laminate comprises a carrier film 20 having a metallic layer 22 provided on one surface thereof, and may also have a second metallic layer 21 provided on its opposite surface. The said opposite surface of the film 20 is secured to a backing film 23 by way of an adhesive 24, while the metallic layer 22 is covered by a preferably transparent coating film 25. <IMAGE>
Description
SPECIFICATION
Metallised film laminate
This invention relates to a metallised film laminate, for example for use in the decoration of automobiles.
Figure 1 of the accompanying drawings shows schematically in cross-section a conventional metallised film laminate which is employed for the decoration of motor vehicles. The laminate is composed of a transparent carrier film 10 have a layer 11 of aluminium vacuum-deposited one one of its surfaces, and a backing film 12 secured to the aluminium layer 11 by means of a layer 13 of adhesive. The carrier film 10 is made of a polyester material (typically polyethylene terephthalate) and is approximately 12 microns in thickness, while the backing film 12 is made of polymeric material (such as polyvinyl chloride) and can vary between 100 and 200 microns in thickness. In use, the backing film 12 is secured to an appropriate substrate so that the aluminium layer 11 can be viewed through the transparent carrier film 10.
Because the carrier film 10 is exposed, it is subject to degradation particularly due to the action of ultra-violet light. In order to render the laminate suitable for outdoor use, a protective plastics covering 14 (shown in broken line) must be provided over the carrier film, the covering 14 being both weather resistant and capable of absorbing ultraviolet radiation. The provision of such a covering does, however, incurthe penaltiesthatthe laminate is expensive to protect, it is difficult to process and a loss of brilliance is experienced. Moreover, in some cases the metallic layer 11 may be corroded bythe action of atmospheric moisture. Furthermore, the choice of materials which can be used for covering 14 is severely limited due to their need to adhere effectively to the polyester carrier film 10.
According to the present invention, a metallised film laminate comprises a carrier film, a backing film adhered to one surface of the carrier film, a metallic layer provided on the opposite surface of the carrier film, and a coating film provided over the metallic layer.
Because the metallic layer is interposed between the coating film and the carrier film, the latter is effectively protected from the effects of ultraviolet light. Moreover, since the coating film no longer has to adhere directly to the carrier film, it is possible to employ a much wider variety of compositions and thicknesses for the coating film than has previously been possible. These coating impart to the laminate the benefits of their own particular characteristics, for example weather resistance, colour, abrasion resistance and ready printability. This in turn increases the versatility of application of the laminate, enabling new decorative effects to be created.
Preferably, the coating film is substantially transparent.
In a particular embodiment of the invention, a second metallic layer is provided on said one surface of the carrier film, and the backing film is adhered to the second metallic layer.
Although the carrier film may still be made of polyester material, unlike in the conventional laminate described above it is possible to employ successfully other polymeric materials, such as nylon, or polypropylene.
Figure 2 shows by way of example a metallised film laminate according to the invention. The laminate is composed of a carrier film 20 made of a polymeric material (such as polyethyleneterephtha- late or nylon) and having layers 21 and 22 of aluminium vacuum deposited on both of its opposite sides, respectively. A backing film 23 made of polymeric material (such as polyvinyl chloride, polycarbonate or polypropylene) is secured to the aluminium layer 21 by means of a layer 24 of adhesive, while the aluminium layer 22 is covered by a transparent film 25 of plastics material, the particular material employed being dependent upon the intended application and the desired properties of the finished laminate. Examples of suitable materials for this purpose are vinyl resins, acrylic resins, cellulose acetobutyrate and ionomer resins.
In an alternative example of the invention (not illustrated), the aluminium layer 21 is omitted and the backing film 23 is adhered directly to the carrier film 20.
In addition to the advantages mentioned above the present invention provides greatly improved brilliance and improved outdoor durability for the laminate.
1. A metallised film laminate comprising a carrier film, a backing film adhered to one surface of the carrier film, a metallic layer provided on the opposite surface of the carrier film, and a coating film provided over the metallic layer.
2. A laminate as claimed in claim 1, wherein the coating film is substantially transparent.
3. A laminate as claimed in claim 1 or 2, wherein a second matallic layer is provided on said one surface of the carrier film, and the backing film is adhered to the second metallic layer.
4. A laminate as claimed in claim 1,2 or 3, wherein the carrier film is made of polymeric material.
5. A laminate as claimed in claim 4, wherein the carrier film is made of polyester, nylon, polypropylene or polyethylene terephthalate.
6. A laminate as claimed in any preceding claim, wherein the backing film is made of polymeric material.
7. A laminate as claimed in claim 6, wherein the backing film is made of polyvinyl chloride, polycarbonate or polypropylene.
8. A laminate as claimed in any preceding claim, wherein the coating film is made of vinyl resin, acrylic resin, cellulose acetobutyrate or ionomer resin.
9. A laminate as claimed in any preceding claim, wherein the or each metallic layer is made of aluminium.
10. A metallised film laminate substantially as hereinbefore described with reference to Figure 2 of the accompanying drawings.
