ABSTRACT:
Electroerosion recording materials are provided with a surface lubricant film of lubricating conductive material in a polymeric binder. The lubricating conductive agent reduces stylus scratching of the conductive layer during electroerosion printing, improves contrast, provides a beneficial coating on the writing electrode or stylus and improves the handling and writing characteristics of the recording material. The lubricating conductive agent/polymer films are especially useful where the substrate of the recording material is light transmissive and, after the electroerosion process, the resulting product is suitable for direct-negative applications.
