Abstract
Cationic radiation curable inks do not exhibit ghosting when coated over by a solvent, solventless and radiation curable silicone release coatings. When aggressive solvent borne adhesives are cast over the ink applied to a substrate, and peeled off after drying, no ghosting is observed. The result is the ability to print graphics onto a substrate and cover the substrate with a silicone release coating and a coat with an adhesive layer that retains acceptable clarity after removal of the release coating.
