Abstract: This disclosure is directed to a plate design for use in variable data digital lithographic image forming devices. The disclosed plate design incorporates surface passivated carbon black filler material particles in a fluorosilicone polymer. The disclosed functionalized carbon black material compositions include hydrophobic carbon black particles passivated with polymerized pentafluorostyrene. The disclosed surface passivated carbon black particles have a diameter in a range of 50 nanometers to 1 micron, and enable enhances dispersion in fluorinated polymers, and fine dispersion in solvent. The disclosed surface passivated carbon black particles are particularly usable for improving operational characteristics of fluorosilocone-based reimageable surface layers of imaging members employed in the variable data digital lithographic image forming devices.
