A thermal transfer sheet is provided which comprises: a foundation; a recording agent layer provided on one side of the foundation; and a back layer provided on the other side of the foundation and containing a binder resin and a charge-transfer complex; wherein the charge-transfer complex comprises an electrically conductive organic polymer serving as an electron donor and an electron acceptor; and wherein the back layer has a surface resistivity of not greater than 10.sup.11 .OMEGA./cm.sup.2.

Thermal transfer sheet

By the selective use of a homogeneous stable precursor solution in which no polymerization reactions immediately occur and which contains aromatic compounds such as pyrrole, thiophene, aromatic amines or their derivatives, oxidizing agents, and solvents, as a precursor solution of conductive polymer film, a homogeneous and tough conductive polymer film can be obtained when the said precursor solution is cast on a substrate and the solvents are evaporated to remove.

Method for the preparation of conductive polymer film

Pyrrole monomer

Polymers of 3,4-substituted pyrrole compounds and their preparation
