Abstract
An energy curable coating composition is provided for use as an overprint varnish on cellulosic, polymeric and metal substrates. The coating composition includes an epoxy acrylate, a triacrylate, and optionally, a diacrylate. The coating composition is applied to a substrate and cured by radiation to form a thermoformable protective coating. The coated substrate may then be thermoformed into a shaped food package or article.
