Abstract: Disclosed are undercoat layers comprising a metal oxide, a polymer, and a citrate of Formula (I): wherein R1 is H, alkyl, or COR?; wherein R? is alkyl; and wherein R2, R3, and R4 are independently alkyl. The undercoat layers are useful in imaging members because they are easily separated from the substrate. This reduces the number of steps necessary to reclaim the substrate.
