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.

摘要： To transfer a toner image from a toner-treated surface, a toner transfer film is employed, which comprises a transparent base carrying a transparent layer which is capable of picking up toner and has a temporary slight surface tack, the layer consisting of a mixture containing a polymeric and/or pre-polymeric binder, a polymerizable low molecular weight compound and a polymerization initiator. After transfer, the toner image can be permanently fixed to the toner transfer film by heating the film and/or exposing it to light.
