Aqueous ink jet blanket

摘要

Described herein is a transfer member for use in aqueous ink jet printer. The transfer member includes a surface layer of a cross-linked polydiphenylsiloxane network formed from a silanol terminated dialkylsiloxane-diphenylsiloxane copolymer and a trialkoxy- or trihydroxysilane terminated polydialkylsiloxane. The diphenylsiloxane moieties are from about 5 weight percent to about 80 weight percent of the network. The trialkoxy- or trihydroxysilane terminated polydialkylsiloxane are from about 1 weight percent to about 60 weight percent of the network. All silane molecules are bonded together via silicon oxide (Si—O—Si) linkages in a single system. The network is insoluble in solvents selected from the group consisting of: ketones, chlorinated solvents and ethers.
