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.

Intermediate transfer member and method of production thereof

According to an example, a resin, a carrier liquid, and a pearlescent pigment may be mixed to form a liquid electrophotographic ink.

Electrophotographic ink including pearlescent pigment

Disclosed herein is an electrostatic ink composition. The composition may comprise a carrier liquid, which has suspended therein: thermochromic pigment particles having a layer of thermoplastic resin thereon. Method for forming electrostatic ink composition and a substrate having the electrostatic ink composition printed thereon are also disclosed herein.

Electrostatic ink compositions

Herein is described a liquid electrostatic ink composition comprising a carrier liquid, a resin, a colorant selected from a magenta colorant, a cyan colorant and a black colorant, an amine-containing basic dispersant having a total base number (TBN) in the range of about 10 to about 65 mgKOH/g material, the amine-containing basic dispersant present in an amount from about 5 wt. % to about 40 wt. % by total weight of colorant.

Liquid electrophotographic ink composition

Herein is disclosed a magenta liquid electrostatic ink composition comprising chargeable particles comprising a resin, a pigment, a liquid carrier in which the chargeable particles are dispersed, and a charge director, wherein the resin is formable from polymerizing alkylene monomers and methacrylic or acrylic acid monomers, the pigment is selected from pigment violet 19 type &#x3b1;pigment violet 19 type &#x3b1;pigment violet 19 type &#x3b2;, pigment violet 19 type &#x3b3;, pigment red 177, pigment red 208, pigment red 122 and pigment violet 32, and the liquid electrostatic ink composition lacks any other types of pigment. Also disclosed herein is a method of electrostatic printing and a print substrate having printed thereon the magenta liquid electrostatic ink composition.

Herein is disclosed a magenta liquid electrostatic ink composition comprising a carrier liquid; and ink particles comprising a resin, a magenta pigment and a black pigment, wherein the black pigment is present in the composition in an amount of 0.01 to 0.5 wt % by total solids of the composition.
