    摘要: Electrostatic printing apparatus and intermediate transfer members Herein is disclosed an intermediate transfer member for use in an electrostatic printing process, the intermediate transfer member having an outer release layer comprising a polysiloxane that has been cross-linked using an addition cure process such that it contains Si—R—Si bonds, wherein R is an alkylene moiety, and a monoalkenylsiloxane has been reacted with and incorporated into the polysiloxane. An electrostatic printing apparatus comprising the intermediate transfer member is also disclosed.

    摘要: Herein is disclosed a method of coating a web with a release formulation. The method comprising: providing a coating station comprising a rotatable applicator roller to apply a release formulation coating to a web; applying a release formulation coating to a surface of the applicator roller, the release formulation comprising at least one silicone oil; feeding the web through the coating station such that the web engages with the applicator roller; and applying the release formulation coating to the web under a shearing force by rotating the applicator roller such that, at a location at which the web and the applicator roller engage, the surface of the applicator roller moves in the opposite direction to the direction the web is fed through the coating station.
