Definitions

• the present invention relates to a metallized decorative film and a process for making it by applying the metallic film by transfer lamination.
• the decorative film can be used to apply decoration to a desired substrate, e.g., a motor vehicle..
• Metallized decorative films which are suitable for exterior use and which contain a substantially transparent, plasticized film have been formed in the past by laminating the transparent film to a vacuum metallized film, e.g., a vacuum metallized polyester film, which is then overlaminated with a clear polyvinyl fluoride film which aids in protecting the polyester film from ultraviolet degradation.
• a vacuum metallized film e.g., a vacuum metallized polyester film
• a clear polyvinyl fluoride film which aids in protecting the polyester film from ultraviolet degradation.
• Such complex laminates are rather stiff and difficult to form into complex shapes and are subject to moisture degradation at the exposed edge of the lamination between the polyvinyl fluoride film and the polyester film.
• the present invention is a metallized decorative film laminate and the process for making it.
• the laminate comprises: (a) a substantially transparent plastic film; (b) a thin metallic layer having one side attached to one side of the plastic film by means of an adhesive layer; and (c) a pressure sensitive adhesive layer attached to the other side of the metallic layer, said adhesive layer being optionally covered on its exposed surface by a release liner.
• the film laminate is formed by applying the metallic layer to one side of the plastic film by transfer lamination followed by attachment of the pressure sensitive adhesive layer and, if desired, release liner to the other side of the metallic layer.
• Figure 1 shows the substantially transparent plastic film to which the metallized layer is to be attached
• Figure 2 shows the plastic film/metallic layer combination after the latter has been adhesively attached to the plastic film by transfer lamination and as the carrier film in the transfer laminate responsible for the transfer lamination step is being removed;
• Figure 3 shows the laminate from Figure 2 after application of a tie coat to the protective or release coating remaining from the transfer laminate used in the previous step
• Figure 4 shows a desired end product after a release liner and pressure sensitive adhesive have been attached to the tie coat in the laminate of Figure 3.
• Figure 1 shows the substantially transparent plastic film 1 which may be any conventional, substantially transparent and flexible film known to persons of ordinary skill in the art of fabricating decorative pressure sensitive products.
• the term "substantially transparent” as used herein is intended to encompass those plastic films which are transparent enough to allow a viewer to perceive the decorative effect generated by the metallic layer in the laminate of the present invention.
• the thickness of the film 1 can range from about 0.05 mm. to about 0.5 mm., and the film can be a homo- or copolymer of vinyl chloride (the preferred film material), a polyester resin, a cellulose resin, or the like. Films of this type are well known in the art and have been used heretofore in forming decorative laminates which differ in construction from the present laminate.
• Figure 2 shows the laminate subcombination that results when a thin metallic layer 2 is adhesively attached to the plastic film 1. This is accomplished by transfer laminating this layer 2 to the film 1 by means of a "metallized transfer laminate" which is indicated generally by the reference numeral 10 in Figure 2.
• metallized transfer laminate Such laminates are well known but have not hitherto been used to laminate thin metallic layers to the type of substantially transparent plastic film used herein to form decorative metallized laminates useful as decorative trim, for example, on such substrates as motor vehicles, and the like.
• Preferred metallized transfer laminates of this type are available under the trademark "Chromtex" from Kurz-Hastings, Inc., Philadelphia, Pa.
• the metallized transfer laminate comprises an adhesive layer 3 attached to a thin metallic layer 2 which is bonded to a carrier film 4, preferably by means of a protective or release coating 5.
• the metallized transfer laminate 10 is applied to the substantially transparent film 1 in such a way so as to adhesively bond metallic layer 2 to film 1.
• the carrier film 4 in the metallized transfer laminate 10 is then stripped off as shown in Figure 2.
• the carrier film 4 may be formed of a suitable flexible material capable of being coated, if desired, by the resinous solution which constitutes the protective or release coating 5.
• suitable carrier films 4 are formed from polyethylene terephthalate, crystallized copolymers of polyethylene terephthalate and isophthalate, oriented polystyrene, polyvinyl flouroide, acetate coated paper, and polyolefins, such as polyethylene and polypropylene.
• the carrier film 4 can have a thickness of from about 0.013 mm. to about 0.125 mm.
• the protective or release coating 5 is preferably included in the metallized transfer laminate 10 since it aids ⁇ n stripping the carrier film 4 from the laminate construction after the metallic layer 2 has been adhesively bonded to transparent film 1.
• the release coating 5 may be formed by coating the carrier film 4 and is preferably a resinous solution comprising solvents which do not adversely affect the film 4 and an organic solute not normally compatible therewith.
• Some representative release coatings include the polyurethanes, silicones, phenol formaldehyde solutions, solvent systems of polyesters and combinations such as methyl methacrylate, ethylene terephthalate, and ethylene isophthalate and water and organic solvent systems of polyvinyl acetate and polyvinyl chloride.
• the coating used to form release layer 5 may be uniformly applied by conventional coating techniques, such as, direct roller coating, reverse roller coating or by flexographic or rotogravure coating.
• the release coating 6, when dried, constitutes a layer which, while not bonded to the carrier film 4 in any chemical sense, superficially adheres to it.
• the metallic layer 2 which is attached, preferably to the surface of release coating 5, may be formed of any metal such as gold; silver, aluminum, magnesium, titanium, nickel, zinc, copper, chromium, cobalt, selenium or the like.
• Metallic compounds as well as alloy s can also constitute the layer.
• Aluminum or an aluminum alloy are often preferred for reasons of economy and durability.
• the thickness of this layer will generally range from about 500 to about 750 Angstroms to about 12,500 Angstroms.
• the films may be deposited on the release coating 5 by the known thermal evaporation or cathodic sputtering techniques as described in U.S. Patent No. 2,993,806.
• adhesive layer 3 in the metallized transfer laminate 10 will depend upon the character of the plastic film 1 to which it will be attached.
• Heat activatable adhesives that are compatible with plastic film 1 can be used and include rubber-phenolic and polyester-isocyanate systems, polyurethane, and solutions of vinyl chloride/ vinyl acetate, vinyl acetate/acrylate and vinyl acetate/ maleate copolymers.
• the selected adhesive will dry to a water-white clear film and remain clear even upon outdoor exposure.
• Figure 4 in the Drawings shows a preferred and finished laminate of the present invention wherein a layer of pressure sensitive adhesive 7 and a release liner 8 have been applied to the exposed surface of the tie coat 6.
• the pressure sensitive adhesive 7 which is used in the present laminate may also be any of the pressure sensitive adhesives which are known and conventionally used in the art.
• pressure sensitive adhesives which may be utilized in the product of this invention, they may be based upon any elastomeric material such as: (1) natural rubber; (2) synthetic rubbers including, for example, styrene-butadiene copolymers, polyisobutylene, butadiene-acrylonitrile copolymers, polychloroprene, and polyisoprene; (3) acrylic copolymers containing at least 50 percent, by weight, of a C 4 -C 12 alkyl acrylate ester, i.e., an alkyl acrylate ester wherein the alkyl group contains from 4 to 12 carbon atoms, together with a hardening comonomer, for example, vinyl acetate, styrene, methyl methacrylate, methyl acrylate, ethyl acrylate, e
• a release liner 8 is preferably affixed to the side of the pressure sensitive layer 7 which is furthest removed from film 1.
• the release liner 8 may be any of the release liners known to persons of ordinary skill in the art of making pressure sensitive products including removable, water soluble protective coatings, and the like.
• One preferred liner material is silicone coated release paper having a thickness of from about 0.05 mm. to about 0.3 mm.
• a release liner may not be needed.
• a preferred process for affixing the combination containing the film 1 and the pressure sensitive adhesive 7 and release liner 8 comprises transfer coating.
• a fluid solution of the adhesive 7 is applied to the release liner 8, and the resulting composite is heated to dry the adhesive layer 7.
• the adhesive side of this adhesive/liner laminate is then laminated to the exposed surface of the protective layer 6 at a conventional lamination nip to form the product shown in Figure 4.
• the adhesive layer 7 is brought into contact with a desired substrate and, when properly positioned, pressure is applied to securely affix it to a desired substrate, e.g., a motor vehicle.
• This Example illustrates how one product of the present invention was made under laboratory conditions.
• a transparent polyvinyl chloride (PVC) exterior grade film having a thickness of about 0.07 mm. was laminated to a release coated polyester film which had been metallized followed by coating of the metallized surface with a clear, light stable, heat activatable adhesive ("No. 9353 Chromtex Smooth Gold 78 with 840 adhesive", available from Kurz-Hastings. Inc., Philadelphia, Pa.).
• This metallized transfer laminate was 0.02 mm. in thickness and had its adhesive side laminated to the matte or dull side of the PVC film by passing both films over a series of heated drums. This raised the temperature of the heat activatable adhesive to about 135°C. for proper activation and formation of a satisfactory bond of the metallized transfer laminate to the PVC film.
• the polyester film was then removed from the transfer laminate leaving a PVC film/adhesive/metal layer/release coated intermediate structure.
• a polyurethane polymer tie coat was applied to the release coating.
• the polyurethane polymer that was used was a fully reacted polyurethane polymer supplied as a solution in toluene and isopropanol (available as "Milloxane LS-516" from Millmaster Onyx).
• a layer of about 0.025 mm. of pressure sensitive adhesive was applied to the tie coat layer by means of a conventional transfer technique.
• the adhesive that was used herein was a high molecular weight thermoplastic acrylic terpolymer, which is available as "Durotak 801053" from National Starch and Chemical Corp.
• the wet adhesive is coated directly onto release paper at a thickness of about 0.076 mm. followed by evaporation of the solvent by heating at 100°C. for 2 minutes. This is followed by lamination of the dried adhesive to the tie coat layer by passing the adhesive/release liner laminate and the PVC containing laminate through a laminating nip.
