Claims8
A photoconductor comprising a supporting substrate, a photogenerating layer, a charge transport layer, and a crosslinked overcoat layer comprising a phenolic compound, a phosphite compound and a melamine resin wherein said overcoat layer further comprises a catalyst, said phenolic compound is 1,3,5-tris(4-tert-butyl-3-hydroxy-2,6-dimethylbenzyl)-1,3,5-triazine-2,4,6-(1H,3H,5H)-trione present in an amount of from about 0.5 to about 1.5 weight percent based on the total solids, said phosphite is tris(2,4-di-t-butylphenyl)phosphite present in an amount of from about 0.5 to about 1.5 weight percent based on the total solids, said overcoat charge transport compound is N,N′-diphenyl-N,N-diphenyl-N,N′-bis(3-hydroxyphenyl)-[1,1′-biphenyl]-4,4′-diamine present in an amount of from about 40 to about 70 weight percent based on the total solids, and said catalyst is a toluene sulfonic acid present in an amount of from about 0.5 to about 1.5 weight percent based on the total solids.
