PURPOSE:To obtain a thermal transfer sheet wherein recording having good uniformity and good color density can be attained, by providing a color material layer containing a specific pyrazolone azo pigment on a base film. CONSTITUTION:A thermal transfer sheet has a color material layer containing a pyrazolone azo pigment represented by a general formula (I). In the formula, R represents alkyl group, alkoxyalkyl group which may be substituted, alkyl group, cycloalkyl group, tetraphdrofulfuryl group, fulfuryl group, or aralkyl group. Ink is prepared by dissolving or dispersing, in a particulate state, this pigment together with binding agent in solvent. The ink is applied on the base film and dried to obtain a color material layer. The thermal transfer sheet coated uniformly with a pigment which is suitable for obtaining full color recording of good color reproducibility and easily sublimed and by which recording of high color density can be obtained at a high speed, is obtained. |
