る。Action / Effect According to the present invention, the antistatic treatment is performed by providing the antistatic layer on the back surface (the surface opposite to the surface on which the thermal transfer layer is provided) of the thermal transfer sheet. The thermal transfer sheet is less likely to be charged when recording is performed by combining the thermal transfer sheet with the thermal transfer sheet, and wrinkles caused by the mutual suction of both sheets and the difficulty of being peeled off after recording are eliminated. Since dust is prevented from adhering, the occurrence of missing recording and unevenness is minimized.

し、乾燥して受容層を形成した。Example 1 (Heat Transfer Sheet) A cast-coated paper (basis weight of 110 g / m 2 ) was coated with a methyl ethyl ketone / toluene (1/1) solution of a thermoplastic polyester resin on one side so that the solid content was 10 g / m 2. Then, it was dried to form a receiving layer.

After coating and winding after coating without drying, it was confirmed that the curl of the sheet was corrected and the antistatic agent coating layer also had a humidity control effect as compared with before coating.

１と同様にして記録を行ない、同様の結果を得た。Example 2 The thermal transfer sheet was the same as in Example 1, except that the back side was replaced with an aqueous solution of an antistatic agent and a back layer coating composition having the following composition was used to apply 5 g / m 2 (when dry). Was recorded in the same manner as in Example 1, and similar results were obtained.

The processed and dried sheet is used, the sheet to be transferred in Example 1 is used (Example 3), and the sheet in Example 2 is used separately (Example 4). When recording was performed in the same manner as in Example 1, wrinkles, dust adhesion, and image loss were further reduced as compared with those in Examples 1 and 2, and the number was extremely small.
