An embodiment of the present disclosure is directed to a sacrificial coating composition for an image transfer member in an aqueous ink imaging system. The coating composition is made from ingredients including: a latex having polymer particles dispersed in a continuous liquid phase; at least one hygroscopic material; at least one oil-in-water emulsion; and at least one surfactant.

Sacrificial coating for intermediate transfer member of an indirect printing apparatus

A curable ink including at least one monomer, oligomer, or prepolymer; an optional photoinitiator; an optional colorant; and amide gellant having a molecular weight of from about 800 to about 2,500 g/mole; wherein the ink has an onset of gelation defined by the glass transition of the low molecular weight amide gellant according to the relationship Onset of Gelation (K)=(Constant) Tg of gellant (K); wherein the Constant is less than 1.5. A process for printing a three-dimensional article including providing a curable ink; depositing the curable ink in one or more layers; and curing the deposited ink to form the three-dimensional object.

Ink jet ink compositions for digital manufacturing of transparent objects

A curable ink composition for forming a three-dimensional (3D) object via a digital additive manufacturing system is provided. The composition may comprise greater than about 30 weight % of one or more oligomers, at least two monomers comprising a lowest viscosity monomer and a highest viscosity monomer, one or more photoinitiators, and optionally, one or more additives. The ratio of the weight % of the total amount of oligomers to the weight % of the total amount of monomers may be at least about 0.5 and the ratio of the weight % of the lowest viscosity monomer to the weight % of the highest viscosity monomer may be at least about 5.
