Electrophotographic recording element containing a naphtholactam dye sensitizer
 An electrophotographic recording element comprising PA1 (A) an electrically conducting base and PA1 (B) at least one photoconductive layer consisting essentially of PA2 (b.sub.1) at least one binder, PA2 (b.sub.2) at least one sensitizer which on exposure of layer (B) generates charge carriers and which is selected from the group of the naphtholactam dyes of the general structure I ##STR1## where the indices and variables have specified meanings, (b.sub.3) at least one photoconductor which transports the generated charge carriers and optionally PA2 (b.sub.4) additives, and also novel naphtholactam dyes of the general formula I where R.sup.2 is substituted monocyclic 1,3-thiazolyl bonded to the naphtholactam structure via a carbon ring atom, the use of these novel naphtholactams I in electrophotographic and laser-optical recording elements and also novel reprographic processes and novel processes for producing offset printing plates and photoresists using the novel electrophotographic recording element.
