Abstract
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.
