Abstract
For high speed electroerosion recording, this invention provides a polyorganosiloxane overlayer which includes high lubricity solid particles as a filler. The overlayer provides a combination lubricant and protective layer for the thin metal layer which is removed by electroerosion to prevent damage for the areas not removed by electroerosion. The polyorganosiloxane overlayer is preferably crosslinked, and is relatively hard, durable, and especially resistant to thermal degradation by the electroerosion arcing. This is important to avoid debris buildup at the recording electrodes resulting from the high temperature arcing for removal of the overlayer in the areas where recording takes place.
