Patent number: 6904252Abstract: An image-bearing article used in liquid contact electrostatic printing (CEP) is formed from polymers that meet the requisite conformance and heat stability for the CEP process. Excessive absorption of toner carrier liquids by the image-bearing article in liquid CEP leads to the deterioration of the image-bearing article and reduces the useful life of the image-bearing article. The absorption of the toner carrier fluid may be controlled by the addition of oxides, silicone elastomers containing phenyl end groups, fluorosilicones or increasing the cross-linking density of the methyl silicones.Type: GrantFiled: March 26, 2003Date of Patent: June 7, 2005Assignee: Xerox CorporationInventors: Constance J. Thornton, Joseph Mammino, Robert M. Ferguson, Paul J. Brach, Edward Scales, Raymond K. Crandall, Edward L. Schlueter, Jr.
