A holographic article and method for forming permits the party producing the final document to print the holographic image directly on the final document thereby permitting such party to retain and maintain control of its own embossing shim on which the hologram has been formed and which is utilized for embossing the holographic image on the document. A film upon which a holographic image can be directly stamped upon the final document includes a layer of metal having a thickness in the range of 20 millimicrons to 100 millimicrons, a lacquer coating having a thickness in the range of 0.5 microns to 3 microns and a heat activatible adhesive. The metal layer lacquer coating and heat activatible adhesive are caused to be adhered to the substrate forming the final document during a stamping operation which releases said metal layer, lacquer coating and heat activatible adhesive from a plastic carrier film to which had initially been applied. |

DETAILED DESCRIPTION I claim: 1.
A method for forming a composite sheet adapted to apply a holographic image directly to a substrate comprising the steps of: (a) providing a film of material selected from the group consisting of a polyester, biaxially oriented polypropylene, cellulosic triacetate, polystyrene, polyethylene and polyvinylchloride; (b) depositing on said film a layer of metal having a thickness in the range of 20 millimicrons to 100 millimicrons; (c) applying to said metal layer a first lacquer coating having a thickness in the range of 0.
5 microns to 3 microns, said first lacquer coating being a member selected from the group consisting of acrylic, styrene-acrylonitrile polymer, polyester and nitrocellulose; (d) applying to said first lacquer coating a second lacquer coating having a thickness in the range of 0.
05 microns to 0.
2 microns, said second lacquer coating being a member selected from the group consisting of acrylic, styrene-acrylonitrile polymer, polyester and nitrocellulose; and (e) applying to said second lacquer coating a heat activatible adhesive having a thickness in the range of 0.
75 microns to 4 microns.
2.
A method for forming a composite sheet adapted to apply a holographic image directly to a substrate comprising the steps of: (a) providing a film of material being a member selected from the group consisting of a polyester, biaxially oriented polypropylene, cellulosic triacetate, polystyrene, polyethylene and polyvinylchloride; (b) depositing on said film a release coating, said release coating being a member selected from the group consisting of wax and siloxane; (c) depositing on said film a layer of metal having a thickness in the range of 20 millimicrons to 100 millimicrons; (d) applying to said metal layer a first lacquer coating having a thickness in the range of 0.
5 microns to 3 microns, said first lacquer coating being a member selected from the group consisting of acrylic, styrene-acrylonitrile polymer, polyester and nitrocellulose; (e) applying to said first lacquer coating a second lacquer coating having a thickness in the range of 0
