Abstract
Abstract A security medium, secure articles made therefrom and methods of making same. Articles are disclosed which are resistant to counterfeiting and unauthorized alteration and which are suitable for use as currency, securities, security passes, identification cards, and analogous items now usually manufactured on paper. The novel articles comprise two synthetic material layers with a barrier layer therebetween and an image formed from sublimatable dye within at least one of the synthetic layers.
