ABSTRACT:
A flexible fog free mirror device for contact attachment and support on a planar surface is disclosed. A three-layered structure includes a first film sheet having an organic coating of anti-fog material on one side. The other side of the sheet has an adhesive coating for laminating the sheet to a first side of a second film sheet. The second side of the second sheet has a reflective metal coating for providing a mirrored finish. The reflective metal coating is laminated to a first side of a cling vinyl film sheet. The vinyl sheet enables the three-layer structure to contact adhere to the planar surface. In an alternate embodiment, a two-layered structure includes the first film sheet and the second film sheet for releasable attachment to an existing mirrored surface. The first film sheet has the organic coating of anti-fog material coated on the one side, the other side of which is coated with a pressure sensitive adhesive. The first side of the second film sheet has a release coating of silicone compound so that the second film sheet may be stripped from the first film sheet to expose the pressure sensitive adhesive layer. As such, the first film sheet may be adhered to the mirrored surface whereby the mirrored surface remains fog-free in a high humidity environment. A printed indicia is included on the other side of the first film sheet.
