A thermal transfer dye donating material comprising a support having thereon a dye donating layer which contains a thermo-mobile dye, wherein the thermo-mobile dye is a dye which can be represented by the general formula (I) indicated below.A--(L--B).sub.q (I)In this formula, A represents a dye residue which has an absorbance in the visible region and/or infrared region, L represents a divalent linking group or a simple bond, and B represents an atomic grouping which has the effect of suppressing the fading of the dye. Moreover, q is 1 or 2, and when q is 2, L and B may be the same or different.
