Production of laminated film.

摘要

A process of producing laminated films which have stable and strong adhesive strength and heat resistance immediately after the lamination has been carried out, which comprises: coating a photocurable adhesive on a first synthetic resin film or a metal foil, the adhesive comprising a polyurethane poly(meth)acrylate and a coupling agent selected from the group consisting of silane coupling agents, titanate coupling agents and aluminum coupling agents; laminating the first synthetic resin film or metal foil to a second synthetic resin film or metal foil; and applying ultraviolet ray or radiant ray to the resultant laminated film.
