Abstract

A decorative film laminate is disclosed comprising: (a) a substantially transparent plastic film; (b) a thin metallic layer having one side attached to one side of the 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.

Claims

1. A method of forming a decorative film laminate which comprises a substantially transparent plastic film, a thin continuous metallic layer adhesively attached to one side of the plastic film, and a layer of pressure sensitive adhesive attached to the thin continuous metallic layer on the side of said metallic layer that is remote from the side attached to the plastic film, said method comprising:

(a) adhesively attaching a metallized transfer laminate to one side of the substantially transparent plastic film, said transfer laminate having the thin continuous metallic layer attached to a carrier film;

(b) stripping the carrier film from the product resulting from Step (a); and

(c) attaching a layer of pressure sensitive adhesive to the side of the metallic layer which is remote from the side attached to the substantially transparent film.

2. A method as claimed in claim 1 which further comprises applying a resinous tie coat to the product resulting from step (b) prior to application of the layer of pressure sensitive adhesive.

3. A method as claimed in claim 1 wherein the pressure sensitive adhesive is attached to a release liner when attached to the metallic layer.
