Abstract

Abstract A thermal transfer image receiving sheet comprises a substrate sheet and a receptor layer disposed on at least one surface of the substrate sheet, wherein the thermal transfer image receiving sheet contains sulfonated polyaniline as an antistatic agent. The sulfonated polyaniline may be contained in the receptor layer or another layer additionally formed on a front or back surface side of the thermal transfer image receiving sheet.
