A process for multi-gradation thermal transfer recording which provides a receptor with an image of multi-gradation, the process comprising placing on the receptor a heat-sensitive transfer material comprised of a substrate film, an adhesive layer on one surface of the substrate film, a heat-melting ink layer thereon and a transfer-control layer formed on the heat-melting ink layer, and charging the heat-sensitive transfer material with various levels of energy depending upon image signals from the substrate side to allow the heat-melting ink of the heat-melting ink layer to transfer to the receptor in an amount that corresponds to the various levels of energy, and a multi-gradation heat-sensitive transfer material to be used in the above process.

Process for thermal transfer recording and heat-sensitive transfer

This invention provides a heat-sensitive transfer layer which comprises a substrate and a heat-melting ink layer provided to one surface of said substrate, characterized by providing, between said substrate and heat-melting ink layer, an interlayer which breaks away within itself by separation under heat at the time of heat transfer.
