Patent ID: 7279506

Claim:
An overprint composition capable of being ink-jetted, comprising: a radiation curable oligomer selected from the group consisting of unsaturated acrylate resins having a viscosity of less than about 0.5 Pa.s at 23° C.; a radiation curable monomer selected from polyfunctional alkoxylated, or polyalkoxylated, acrylic monomers comprising one or more di- or tri-acrylates; at least one photoinitiator; and at least one surfactant, wherein the overprint composition has a viscosity ranging from about 15 cP to about 8 cP at a temperature ranging from about 40° C. to about 70° C. and a surface tension ranging from about 20 to about 30 dynes/cm at about 40° C. to about 70° C.; and wherein the oligomer:monomer ratio is about 1:4.
