Photosensitive element having an aluminum base and silane intermediate layer

摘要

A sensitized lithographic printing plate is produced from an aluminum base which has been mechanically, chemically and/or electrochemically pretreated and anodically oxidized in a conventional manner and a photosensitive copying layer which is applied to this base, by a process in which a thin layer which imparts hydrophilic properties and consists of a hydrolysis product or condensate of one or more silanes is applied between the base and the copying layer. These lithographic printing plates are particularly useful for offset printing.
