Abstract
The present invention relates to an imaging element, which comprises:a support having a front and rear surface;a transfer layer having a melting point of at least 65° C. and which is capable of transferring and adhering developed image and non-image areas from said front surface of said support upon the application of heat energy to the rear surface of the support, the transfer layer strips from the front surface of the support by liquefying and releasing from the support when heated, said liquefied transfer layer providing adherence to a receptor element by flowing onto the receptor element and solidifying thereon, the adherence does not require an external surface adhesive layer; andat least one layer of microcapsules or at least one layer of microcapsules and developer in the same layer or separate layers.The present invention further relates to a method of transferring a photographic image to a receptor element.
