When the reflection density of the colorants of an ink layer is 1.3 after transfer onto a recording paper, a reflectance of yellow colorant lies in between two diagrams (D.sub.1, D.sub.2) shown in FIG. 1, a reflectance of magenta colorant lies in between two diagrams (D.sub.3, D.sub.4) shown in FIG. 2, and a reflectance of cyan colorant lies in between two diagrams (D.sub.5, D.sub.6) shown in FIG. 3. A color ink sheet realizes an excellent hue, a high luminance factor and high chroma. A wide color specification range and clear image having a high color reproducibility is obtained.
