Abstract (en)
The problem of crystallization of organic photoconductive compounds in insulating binder-containing layers, which may impair the capability of those layers to produce high-resolution images, is overcome by using as the photoconductor a mixture comprising at least two compounds of the formula: <CHEM> wherein R is an alkyl, substituted alkyl, aralkyl, aryl or substituted aryl group; each of X, X min , Y, and Y min , which may be the same or different is hydrogen, alkyl, substituted alkyl, alkoxy, substituted alkoxy, hydroxyl, nitro or halogen; each of A and B, which may be the same or different, is hydrogen, alkyl, substituted alkyl, alkoxy, substituted alkoxy, hydroxyl, halogen, unsubstituted or substituted aryl, cycloalkyl having four to ten carbon atoms and cycloalkenyl having four to eight carbon atoms; or A and B taken together represent atoms which form with the carbon to which they are attached a substituted or unsubstituted carbocyclic ring having from 4 to 10 atoms, any alkyl, substituted alkyl, alkoxy or substituted alkoxy substituent having from 1 to 10 carbon atoms and any aryl or substituted aryl group being an unsubstituted or substituted phenyl, naphthyl or anthryl group, any substituent in a substituted aryl group being an amino, alkylamino, or dialkylamino group or a substituent as defined for X, X min , Y and Y min .
