An ink composition for use in digital offset printing including at least one component selected from the group consisting of a curable monomer and a curable oligomer; an optional dispersant; an optional photoinitiator; and at least one non-radiation curable additive, wherein the non-radiation curable additive is a detergent or an emulsifying agent, or wherein the non-radiation curable additive functions as a detergent or emulsifying agent when in the presence of a cleaning fluid, and wherein the non-radiation curable additive is a solid at a temperature of from about 20&#xb0; C. to about 40&#xb0; C.

An aqueous ink composition including water, an optional co-solvent, a sulfonated polyester, and a polyurethane dispersion, and process of making thereof.

Sulfonated polyester ink

An ink composition useful for digital offset printing applications includes a colorant and a high viscosity thickening agent. The ink is formulated to incorporate polyester viscosity modifier to help meet the requirement of two different viscosity or temperature pairs at two different stages of the process. In digital offset printing a bulk ink is first transferred onto an anilox roll, and then from the anilox roll onto the imaging cylinder blanket. During the bulk ink to anilox roll the disclosed ink has a low viscosity while the transfer from roll to imaging blanket the ink has a higher viscosity. The addition of the polyester viscosity modifier increases the viscosity difference within the allowable temperature range, thus, increasing process latitude and robustness.

Phase-change digital advanced lithographic imaging ink with polyester transfer additive

A nanoscale pigment particle composition includes an organic monoazo laked pigment including at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, wherein the mono-azo laked pigment includes a nono-azo dye molecule laked with a divalent metal cation; the functional moiety associates non-covalently with the functional group; and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized pigment particles. Non-aqueous dispersion compositions, such as ink compositions, contain a polymeric dispersant, an organic liquid, and the nanoscale pigment particle composition.
