A thermal transfer recording medium comprises a substrate and an ink layer formed on the substrate. The ink layer comprises a first dye having a light absorption peak which has a maximum absorption wavelength, λ max , of 420 to 500 nm and a half-value width of at least 100 nm, and a second dye having a light absorption peak which has a maximum absorption wavelength, X max , of 570 to 650 nm and a half-value width of at least 100 nm. The ink layer may further comprise a third dye having a light absorption peak whose maximum absorption wavelength, λ max , of 500 to 550 nm and/or a fourth dye having a light absorption peak whose maximum absorption wavelength, λ max , of 620 to 680 nm. When a density-graded indication is made using the thermal transfer recording medium, there can be obtained images whose black hue shift is small in all the density range. |
