ABSTRACT:
The present invention relates to an article comprising: a pair of substrates comprising a thermoplastic; a holographic recording medium positioned between the substrates such that the holographic recording medium has at least one exposed area; and an environmental barrier seal protecting the at least one exposed area from environmental degradants; wherein the environmental barrier seal comprises: an inner layer adhered to at least one of the substrates and comprising a thermally meltable adhesive; an outer layer comprising a moisture impervious plastic; and an intermediate layer positioned between the inner and outer layers and comprising an moisture and oxygen impervious metallic foil. The present invention also provides a process for forming such an article.
