  • Undercoat layer and imaging members comprising same
    Patent number: 9228161
    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.
    Type: Grant
    Filed: July 11, 2014
    Date of Patent: January 5, 2016
    Assignee: XEROX CORPORATION

  • Undercoat layers and methods for making the same
    Patent number: 8043774
    Abstract: The presently disclosed embodiments are directed to layers that are useful in imaging apparatus members and components, for use in electrostatographic, including digital, apparatuses. More particularly, the present embodiments provide a robust undercoat layer comprising TiSi in which the TiO2 to SiO2 ratio falls in a particular ratio range discovered to reduce both plywood print defects as well as abnormal operating parameters and print defects from micro-cracks in the undercoat layer, and methods for making the same.
