Abstract
Multi-layer cards with aesthetic and/or functional features, e.g. banking, access, or identification cards, having a bearing layer that includes an effects layer disposed directly between two core layers are disclosed herein. Among other potential benefits, the layered structure of the bearing layer reduces overall manufacturing costs, as compared to methods known in the art, by facilitating a balanced card construction while minimizing the number of layers formed from relatively expensive materials, avoiding direct imaging of the effects layer and minimizing waste associated therewith, as well as providing for reliable incorporation of the effects layer into the multi-layered structure with minimal expenditure of resources and reduced possibility of waste.
