GEPRÄGTES SUBSTRAT UND PHOTORECEPTOR-VORRICHTUNG DIE DIESES BEINHALTET UND VERFAHREN

摘要

An embossed substrate comprising a substrate of a plastic material and having a surface and an embossed surface carried by the surface of the substrate. The embossed surface is characterized by having a pattern with an average roughness of between 100 nanometers and 300 nanometers with the roughness being distributed substantially uniformly over the surface, the pattern has ridges and valleys with the horizontal distance between adjacent ridges and/or valleys being greater than the depth between the ridges and the valleys. The peaks and the valleys are randomly disposed without periodicity to cause diffusion of light impinging thereon to minimize or eliminate interface effects when the embossed surface overcoated with thin planar organic layers is exposed to light.
