Abstract
An ink transfer medium, and a method for manufacturing the medium are provided. The ink transfer medium is of the electrically fusible type, and has an anisotropically electrically conductive layer characterized by greater electrical conductivity in the direction normal to the surface of the layer than in a direction parallel to the surface of the layer. Other layers sequentially provided next to each other, include a resistive layer for converting an electrical signal into heat, a conductive layer, an ink separation layer, and a fusible ink layer. Examples are given illustrating the use of the ink transfer medium. The anisotropically electrically conductive layer may be made by anodizing an aluminum cylinder to form an alumina body defining a plurality of through-pores and electrolytically filling the through-pores with a metal such as nickel or cobalt.
