Abstract
A dye-transfer-sheet in the form of a self supporting film having a total thickness of from 4 to 15 .mu.m and consisting of a layer of one or more thermally mobile sublimation dyes dissolved or dispersed in a polymeric binder and a hydrophilic barrier layer adjacent to, but distinct from the dye-containing layer comprising a polymeric binder substantially impermeable to migration of the sublimable dye(s). The dye-transfer-sheets have a high sensitivity due to the absence of a separate support substrate and are capable of producing clear, high density transferred images.
