    摘要: An image receiving layer for use in non-impact printing, especially in an electrostatographic printing method, is provided with an image receiving surface having a specified ratio between average and maximum roughness and a specified kinetic coefficient of friction against rubber with shore hardness 70. The receiving layer is especially well suited for producing lithographic printing plates with non-impact printing, especially with electrostatographic means.
