Abstract
This invention involves a structure containing a layered imaged configuration with an overcoating layer. The overcoating layer, in addition to encapsulating the toned image, substantially strengthens the dielectric layer after it is removed from the system. Also, a process for producing a product having an image depth perception and the product itself are disclosed. The layered structure may have one or two dielectric layers having a combined thickness of from about 0.2 to about 10.0 mils.
