Abstract
Abstract A printing ink formulation including a blend of a polyester resin and epoxy resin is disclosed for use on polyvinyl fluoride films. The printed polyvinyl fluoride films may be used as the outer layer in laminate structures, where the inert properties of polyvinyl fluoride are desired. In such a laminate structure, the printed surface of the polyvinyl fluoride film is joined to a substrate such as a polyvinyl chloride layer by a laminating adhesive that is based on a polyester resin that is the same as or similar to the polyester resin component of the printing ink formulation.
