1. A method of transferring foil to a substrate in an image pattern comprising:
providing a foil bearing web;
providing a substrate for receiving foil from the web;
applying an adhesive composition to the substrate in an image pattern through a
flexographic printing process, wherein the adhesive composition comprises a monomer component comprising one or more free-radical curing monofunctional monomers;
an oligomer/resin component comprising one or more oligomers, one or more inert thermoplastic resins, or a combination thereof, the oligomer/resin component being soluble in the one or more monofunctional monomers; and
optionally one or more functional additives for curing the adhesive composition upon exposure to UV, LED, or EB radiation;
applying UV, LED, or EB radiation to the image pattern to cure the adhesive composition to a hardened, and tack-free state; and
positioning the substrate bearing the cured image pattern against the foil of the foil bearing web and applying heat and pressure to render the adhesive composition tacky and transfer the foil onto the image pattern.
