Printed release liners
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.
1. A laminate, comprising:
a substrate,
an ink printed on said substrate,
a coaling placed over said printed substrate, wherein the ink comprises a cycloaliphatic resin, bisphenol epoxy resin, polyol, photoinitiator, bubble breaker, surfactant, wetting agent and pigment, and
wherein said coating is silicone.
2. The laminate of claim 1 , wherein said substrate is at least one member selected from the group consisting of nylon, PET, and a polyolefin.
3. A method for making a printed substrate, comprising:
providing a substrate,
printing said substrate with an ink comprising a cycloaliphatic resin, bisphenol epoxy resin, polyol, photoinitiator, bubble breaker, surfactant, wetting agent and pigment
curing said ink, and
applying a release coating to said printed substrate,
wherein said coating is applied by wire-wound rod, direct granite, offset gravure of fibril coating.
4. A method for making a printed substrate, comprising:
providing a substrate,
printing said substrate with an ink comprising a cycloaliphatic resin, bisphenol epoxy resin, polyol, photoinitiator, bubble breaker, surfactant, wetting agent and pigment
