Electroerosion recording materials of superior scratch resistance are provided by incorporating a hard, crosslinked polymer film or layer between the support and the removable, thin conductive layer to reduce plastic deformation of the support under stylus writing pressure. The intermediate polymer layer may be unfilled or filled with solid, particles, such as. silica particles. The materials may be used in various printing processes including making directly readable images, direct negatives, and offset masters. n The drawing shows a cross-section of the material. The layer 2 may comprise a thermoset cellulose-butyrate polum- er crosslinked with isocyanate. |
