Patent ID: 7981580

Claim:
A photoconductor comprising: a photogenerating layer, a bottom charge transport layer in contact with said photogenerating layer, and a top charge transport layer in contact with said bottom charge transport layer, wherein said top charge transport layer, said bottom charge transport layer, or said top and said bottom charge transport layers is comprised of from about 10 to about 75 percent by weight of at least one charge transport compound, and a mixture of a tris(enylaryl)amine and a bis(enylaryl)arylamine, wherein said charge transport compound is an aryl amine selected from at least one of the group consisting of N,N′-diphenyl-N,N-bis(3-methylphenyl)-1,1′-biphenyl-4,4′-diamine, tetra-p-tolyl-biphenyl-4,4′-diamine, N,N′-diphenyl-N,N′-bis(4-methoxyphenyl)-1,1-biphenyl-4,4′-diamine, N,N′-bis(4-butylphenyl)-N,N′-di-p-tolyl-[p-terphenyl]-4,4′-diamine, N,N′-bis(4-butylphenyl)-N,N′-di-m-tolyl-[p-terphenyl]-4,4′-diamine, N,N′-bis(4-butylphenyl)-N,N′-di-o-tolyl-[p-terphenyl]-4,4′-diamine, N,N′-bis(4-butylphenyl)-N,N-bis-(4-isopropylphenyl)-[p-terphenyl]-4,4′-diamine, N,N′-bis(4-butylphenyl)-N,N′-bis-(2-ethyl-6-methylphenyl)-[p-terphenyl]-4,4′-diamine, N,N′-bis(4-butylphenyl)-N,N′-bis-(2,5-dimethylphenyl)-[p-terphenyl]-4,4′-diamine, and N,N′-diphenyl-N,N′-bis(3-chlorophenyl)-[p-terphenyl]-4,4′-diamine, and said mixture is comprised of from about 30 to about 70 weight percent of said tris(enylaryl)amine and from about 70 to about 30 weight percent of said bis(enylaryl)arylamine, the total thereof is about 100 percent, and wherein said bis(enylaryl)arylamine is selected from the group consisting of at least one of N,N-bis-[4-[4,4-bis(4-methylphenyl)-1,3-butadienyl]phenyl]-4-methoxyphenylamine, [4-(2,2-diphenylethenyl)phenyl][4-(4,4-diphenyl-1,3-butadienyl)phenyl]phenylamine, N,N-bis[4-(2,2-diphenylethenyl)phenyl]-4-methylphenylamine, and N,N-bis[4-[2,2-bis(4-methylphenyl)ethenyl]phenyl]-4-methylphenylamine.
