    摘要: Disclosed is a digital information media having an adhesion promotion layer supported on a dummy (L1) substrate that enables secure bonding of the L1 layer, directly or indirectly, to the rest of the stack of layers in the digital information media. Certain materials including metals, metal alloys, or metalloids enhance adhesion between the adhesive layer and the L1. By applying an adhesion promotion layer of such materials on an inner surface of the L1, the bond between the adhesive and the adhesion promotion layer improves bonding and reduces a tendency for the L1 to delaminate from the rest of the stack. The tendency for breakage of the media at the juncture between the adhesion promotion layer and the adhesive is reduced, and incursion of moisture or oxygen through the interface between the adhesion promotion layer and the adhesive is inhibited.
