Abstract
A heat transfer sheet for an electrothermal transfer system including a dye layer containing a heat migratable dye on one surface of a substrate sheet and a resistance layer which generates heat by electrical current flow on the other surface of the substrate sheet. The heat transfer sheet is characterized in that a slip property imparting agent for lowering the frictional resistance between the resistance layer and electrode head during transfer is contained in the resistance layer.
