Definitions
- the present invention relates to a graffiti resistant film and a method for the application of an anti-graffiti coating onto a substrate and is concerned in particular, although not exclusively, with a graffiti resistant self adhesive film and a method for the application of an anti-graffiti coating onto the self adhesive film.
- Known graffiti protective multi-layer films used for display signs, automobile bodywork livery comprise an adhesive backing sheet, a film layer that carries pigment and a transparent protective overlay sheet.
- the protective overlay sheet may be in the form of a clear polyester and vinyl over-laminates.
- Such protective overlay sheets can be laborious to apply and may be susceptible to trapped air bubbles if not applied correctly.
- a method for coating a substrate with a graffiti resistant barrier comprising the use of a screen printing process to apply a liquid layer of graffiti resistant barrier substance to a substrate and allowing the layer of graffiti resistant barrier to dry, characterised in that the method uses a plurality of screen printing stages to apply a plurality of different liquid graffiti resistant barrier substances to the substrate in order to form an image on the substrate.
- screen printing process is used herein for any process of applying a liquid to a surface of a material by squeezing the liquid through the open parts of a mesh on to the surface.
- a mesh stencil may be used in such a process whereby the liquid is squeezed through the open parts of the mesh stencil on to the surface.
- the surface to which the liquid is applied may be of any suitable material for the required function of the final product.
- the surface may be smooth or rough, flat or curved.
- the material used is a flexible self-adhesive vinyl or a substantially rigid plastics material as used in the sign industry.
- a sheet substrate coated with a plurality of different graffiti resistant barrier substances using a method according to the first aspect of the invention.
- the sheet substrate is coated with a graffiti resistant barrier substance using a method according to the first aspect of the invention.
- Previously graffiti resistant paint products have been manufactured to be either painted using a brush or sprayed onto surfaces such as building walls. We have discovered the surprising fact that the characteristics of a 'two pack' type of graffiti resistant paint product allows the composition to be applied using a screen printing process.
- the graffiti resistant substance is substantially transparent when dry.
- the substantially transparent graffiti resistant substance is used to form a barrier over the sheet thus protecting the surface of the sheet and any image or print under the barrier that is applied to the surface of the sheet from potential graffiti.
- the graffiti resistant barrier substance comprises a colour pigment.
- a plurality of graffiti resistant barrier substances that each comprise a different colour pigment.
- the graffiti resistant barrier substances that comprise colour pigments may be used to form an image or print applied to the sheet.
- a further graffiti resistant barrier covering the image or print may not be necessary.
- the sheet substrate is a self-adhesive sheet.
- sheet substrates coated with a graffiti resistant barrier substance according to a second aspect of the present invention have improved fire retardant characteristics that improve the fire performance.
- screen printing apparatus 1 comprising a printing base 2, a frame 4 and a mesh 6.
- the mesh 6 is stretched between and attached to the frame 4.
- a stencil 8 may be placed between the mesh 6 and a stock sheet 9 to define a desired pattern.
- the stock sheet 9 is supported by the printing base 2.
- the stock sheet 9 may be a self-adhesive vinyl sheet as used for a vehicle livery or a rigid plastic sheet as used in the sign industry.
- an ink 10 is forced through the mesh 6 and onto the uppermost surface of the stock sheet 9 using a squeegee 12. Such a process is well known to the skilled person in the art.
- a known multi-laminate film 20 comprises a polyester base sheet 22, a first adhesive layer 24, a print layer 26 and a vinyl protective over-laminate film 30 comprising a second adhesive layer 28.
- the multi-laminate film 20 is manufactured by first placing the base sheet 22 on a screen printing apparatus and applying the print layer 26. Once dry the protective over-laminate film 30 is placed onto the print layer 26 and bonded thereto by the second adhesive layer 28.
- the first adhesive layer 24 is used to fix the multi-laminate film 20 to a desired surface such as a vehicle side. Air bubbles may become trapped between the print layer 26 and the second adhesive layer 28.
- a sheet substrate 40 comprises a base sheet 42, a first adhesive layer 44, a print layer 66 and a coating 48 of a graffiti resistant barrier substance.
- the graffiti resistant barrier substance is preferably a 'two pack' type of graffiti resistant paint product.
- One such two pack anti-graffiti paint is Gardnerlens FTM, which is manufactured by Tremco Limited. We have found that a mix ratio of 59.4% part A to 40.6% part B works particularly well. Although these types of products have been manufactured to be applied to a surface using a brush or spraying device we have discovered the surprising fact that they may be used as a screen printable ink.
- the sheet 40 is manufactured by first placing the base sheet 42 on a screen printing apparatus and applying the print layer 46. Once the print layer 46 is dry the coating 48 of a graffiti resistant barrier substance is applied to the print layer 46 using the screen printing apparatus.
- a sheet substrate 50 comprises a base sheet 52, a first adhesive layer 54 and a print coating 56.
- the print coating 56 comprises a plurality of respective compositions 56a, 56b, 56c, 56d each composition comprising a graffiti resistant barrier substance and a different colour pigment.
- the graffiti resistant barrier substance is preferably a 'two pack' type of graffiti resistant paint product.
- the multi-laminate film 50 is manufactured by first placing the base sheet 52 on a screen printing apparatus and applying a first composition 56a by the screen printing process described above. This operation is repeated for the other compositions 56b to 56d so forming the print coating 46.
