Patent number: 9587127Abstract: The acrylate monomers of the present invention, particularly o-phenyl phenoxyethyl acrylate, provide very fast curing, hard and solvent resistant digital printing inks, and yet are also still surprisingly flexible. These properties make for a technically superior alternative to the widely accepted very hard monomer isobornyl acrylate. O-phenyl phenoxyethylacrylate also has the additional benefit of being free from the strong odor associated with isobornyl acrylate.Type: GrantFiled: January 27, 2014Date of Patent: March 7, 2017Assignee: SUN CHEMICAL CORPORATIONInventors: Shaun Lawrence Herlihy, Jason Wilber, Stephen Anthony Hall, Brian Rowatt
