Patent ID: 7166406

Claim:
An overprint composition, comprising: at least one oligomer chosen from the group consisting of polyether acrylate oligomers, at least one monomer chosen from the group consisting of di-acrylate monomers, alkoxylated di-acrylate monomers, polyalkoxylated di-acrylate monomers, tri-acrylate monomers, alkoxylated tri-acrylate monomers, polyalkoxylated tri-acrylate monomers, at least one photoinitiator, and at least one surfactant; wherein the overprint composition is radiation curable; wherein an oligomer:monomer ratio is in a range of from about 1.5:1 to about 4:1; and wherein the overprint composition-coated print, after curing, has a thermal cracking area value of about 0% to about 0.05% after thermal shock.
