    Abstract: An electrophotographic recording element comprising (A) an electrically conducting base and (B) at least one photoconductive layer consisting essentially of (b1) at least one binder, (b2) at least one sensitizer which on exposure of layer (B) generates charge carriers and which is selected from the group of the isoindolenine dyes of the general structure I where the index and the variables have specified meanings, (b3) at least one photoconductor which transports the generated charge carriers and optionally (b4) additives, in useful for reprographic purposes, for producing printing plates, in particular offset plates, and for producing photoresists.
