Abstract: There is described an intermediate transfer member for digital offset printing, comprising: a cured silicone release layer formed by curing a curable silicone release formulation comprising: a polyalkylsiloxane containing at least two vinyl groups having a weight average molecular weight of 60,000 g/mol or less; a polyalkylsiloxane containing two vinyl groups having a weight average molecular weight of at least 65,000 g/mol; a polyalkylsiloxane cross-linker containing at least two Si—H bonds; and a catalyst or a photoinitiator. There is also described a method of producing an intermediate transfer member, and a curable silicone release formulation for an intermediate transfer member.

Abstract: An intermediate transfer member for digital offset printing, comprising a cured silicone release layer formed by curing a curable silicone release formulation comprising a polyalkylsiloxane containing at least two vinyl groups; an at least partially fluorinated polyalkylsiloxane containing at least two vinyl groups; a polyalkylsiloxane cross-linker containing at least two Si-H bonds; and a catalyst or photoinitiator; wherein fluorine atoms provide at least 2.5 wt.% of the total weight of polyalkylsiloxane compounds. There is also described a method of producing an intermediate transfer member, and a curable silicone release formulation for an intermediate transfer member.
