Abstract
An ink ribbon for use in electrothermic non-impact recording comprising an electroconductive base layer and an electroconductive thermal-transferable ink layer which are layered. The base layer comprises a binder resin and an electroconductive material dispersed uniformly in the binder resin, while the electroconductive thermal-transferable ink layer comprises a thermoplastic material and an electroconductive material uniformly dispersed in the thermoplastic material, with the surface resistivity .rho.b of the base layer being greater than the surface resistivity .rho.i of the ink layer, and the softening or melting point Tm1 of the binder resin in the base layer being higher than the softening or melting point Tm2 of the thermoplastic material in the ink layer.
