Abstract
The present invention relates to an imaging system, which comprises a support having a front and rear surface, at least one transfer layer coated on the front surface of the support, and at least one thermal recording layer coated on top of the outermost transfer layer, wherein the thermal recording layer contains heat-responsive microcapsules capable of separating an inner phase within the microcapsules from an outer phase contained outside the microcapsules, wherein said inner phase is capable of reacting with said outer phase to create a color forming element, and wherein the transfer layer is capable of transferring and adhering an image from said front surface of said support upon the application of heat energy to the rear surface of the support, said transfer layer strips from said front surface of the support by liquefying and releasing from said support when heated, said liquefied transfer layer providing adherence to a receptor element by flowing onto said receptor element and solidifying thereon, said adherence does not require an external adhesive layer, with the proviso that the transfer layer is not capable of reacting to form an image
