A precious metal thin-film laminate (PMTL) () that is presented in terms of a structure and as a process for producing various embodiments of the structure. The PMTL () is comprised of three basic elements: a substrate () having an upper surface () and a lower surface (), a selectable quantity of a precious metal () such as gold () that is deposited onto the upper surface () or onto the lower surface () of the substrate (), and a protective layer () that is applied over the precious metal (). Preferably, the PMTL () also includes indicia () and a PMTL authenticating device (). The PMTL () can be utilized as material for collectible art, traded, and purchased and sold by individuals and/or commercial enterprises.

The present invention provides an improved method for making a solar control sheet having one or more metal layers. In the prior art solar control sheets, each metal layer would normally be non-porous so that water vapor would not be readily transmitted therethrough. However, in this invention the metal layer is rendered porous because it is deposited on a porosity inducing surface. The porosity inducing surface may be the surface of a porous primer layer or a surface which has been roughened. Consequently when the solar control film of this invention is mounted on a window with a water based mounting media, the water can quickly evaporate through the film without causing undesirable cloudiness which is normally associated with water which becomes trapped between the film and the window.

A structure for secure containment of information (SSCI) that is in the form of a laminate which includes at least two layers. The laminate is constructed to contain information such as a code, serial number, informational feature, encryption key or personal identification number (PIN). The information is located between the layer of the laminate such that the code, serial number, informational feature, encryption key, or PIN is not detectable from outside the laminate. The SSCI is configured to provide access and expose the code, serial number, informational feature, encryption key, or PIN by delaminating at least one layer, thereby indicating that tampering has occurred to the laminate. The SSCI can also function as a public key or private key for a blockchain, to provide access to a physical lock or to provide account access to claim financial value.

A metallic sheet with deposited structured images and method for manufacture (MSDIMM) that includes a substrate, at least one structural feature, and a metal layer. The structural feature is at least one cavity on the substrate's upper surface, or at least one material object that extends outward from the substrate's upper surface. The metal layer is deposited, either by sputtering or atomic deposition, onto the substrate's upper surface, and, as the metal layer is deposited, the metal layer interfaces with and follows the dimensions of the structural feature(s), thereby creating a visible image at the location(s) of the structural feature(s). The visible image can be any image, and is preferably either an artistic image, a textual image, or an authentication image. The MDSIMM can be used for a variety of purposes, and is especially effective as a form of exonumia or currency.
