Abstract A multi-gradation heat sensitive transfer medium for use in multi-gradation thermal transfer for adjusting the density of a transfer print image by superimposing ink layers on a recording medium a plurality of times by thermal transfer, which comprises a foundation and ink layers provided thereon, each of said ink layers containing a color pigment having a high transparency and a high tinting strength in an amount smaller than sufficient to provide a maximal degree of reflection density, and each of said ink layers having a light transmittance of not less than about 65% in a region where the color pigment does not have any absorption band. By superimposing the ink layers of the transfer medium on a recording medium a plurality of times, there is obtained a clear print image having a multiplicity of gradations.
A multi-gradation heat sensitive transfer medium for use in multi-gradation thermal transfer for adjusting the density of a transfer print image by superimposing ink layers on a recording medium a plurality of times by thermal transfer, which comprises a foundation and ink layers provided thereon in a side-by-side relationship, each of said ink layers containing a color pigment having a high transparency and a high tinting strength in an amount smaller than sufficient to provide a maximal degree of reflection density, each of said ink layers having a light transmittance of not less than about 65% in a region where the color pigment does not have any absorption band.
