摘要： Coloration resistant photoconductive insulating compositions useful in making elements, such as photoconductive electrophotographic papers, are provided. Such compositions comprise (1) an electrically insulating organic binder, (2) a nitrogen-free polyaryl hydrocarbon photoconductor such as those having the formula ##STR1## wherein: N REPRESENTS AN INTEGER HAVING A VALUE OF 0, 1 OR 2,Ar represents an aryl group including substituted aryl such as phenyl, alkylphenyl having 1 to about 10 carbon atoms in the alkyl moiety, alkoxyphenyl having 1 to about 10 carbon atoms in the alkoxy moiety, and the like,Each of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 represents a hydrogen atom, an aryl group, an alkyl group or an alkoxy group and, when n is O, R.sup.1 and R.sup.4 are both aryl and when R.sup.1 and R.sup.4 are both hydrogen, each of R.sup.2 and R.sup.3 represents an aryl group; and (3) a sensitizer that is substantially non-color forming in the composition. Particularly useful such sensitizers include benzopyrylium type compounds.
