ABSTRACT:
Improved electroerosion recording media are described in which ablatable polymers are used in the electroerosion recording medium. This medium includes at least a substrate or support layer, a base layer which protects the substrate, a thin film of conductive material on the base layer and which can be eroded, and a protective overcoat layer. Ablatable polymers are used as binders in either the base layer or the top protective layer, or both, in order to provide advantages during electroerosion. These ablatable polymers undergo thermally induced depolymerization in such a way that the result is the formation of volatile monomeric or low molecular weight species as the predominant products, with little or no adherent residue.
