Abstract
A thermal transfer sheet comprising a heat resistive base, a thermally transferable ink layer on one side of the base, and auxiliary particles distributed in the layer so that they partially emerge from the surface of the layer to present an irregular surface. The transferable ink layer comprises a mixture of a coloring agent and a hot melt binder, the mixture being transferable to a writing surface in response to application of heat to the other side of the base to provide continuous tone rendition.
