Title: Antistatic coat, thermal transfer sheet having antistatic property and antistatic agent

Abstract: An antistatic coat of the present invention coats a surface of a base body so as to prevent accumulation of electric charges in the base body, the antistatic coat having a multi-layers structure comprising at least one antistatic layer, and the antistatic layer being disposed between the base body and an outermost surface layer of the antistatic coat. On the back surface side of a thermal transfer sheet, there is formed a heat resistant slip layer through an antistatic layer, or a heat resistant slip layer containing a conductive material. Sulfonated polyaniline, a conductive carbon black having primary particle size of up to 40 nm and specific surface of at least 130 m.sup.2 /g, and a conductive carbon black having an oil absorption of at least 75 ml/100 g are favorable conductive material.
