Abstract
The present invention provides an improved electroerosin recording medium which comprises, in a preferred embodiment, a non-conductive support, a hard, abrasion resistant layer, preferably comprising an organic polymer matrix containing an inorganic particulate material, a thin conductive film, typically of a metal such as aluminum, and an abrasion resistant overlayer that most preferably comprises a solid conductive lubricant dispersed in an organotitanium regaent modified polymer system. The overlayer is highly adherent to the conductive surface, has a low organic binder content and provides effective protection against abrasion of the conductive layer and fouling of a print head during electroerosion printing.
