Claims
- 1. A multilayer photoconductor element comprising:
- a support layer;
- a conductive layer adhered to one side of the support layer;
- a barrier layer that is less than about 1.0 micron in thickness, said barrier layer adhered to the conductive layer and consisting essentially of a copolymer of (1) at least one olefinically unsaturated carboxylic acid anhydride containing 4 through 8 atoms per molecule, and (2) at least one vinyl monomer, wherein the weight ratio of (1) to (2) is in the range of about 10:1 to about 1:10;
- a charge generation layer adhered to the barrier layer; and
- a charge transport layer adhered to the charge generation layer wherein the charge transport layer comprises an n-type transport agent.
- 2. The photoconductor element of claim 1 wherein said carboxylic acid anhydride is maleic anhydride.
- 3. The photoconductor element of claim 1 wherein said vinyl monomer is ethylene.
- 4. The photoconductor element of claim 1 wherein said vinyl monomer is styrene.
- 5. The photoconductor element of claim 1 wherein said vinyl monomer is vinyl methyl ether.
