Abstract
A new process for lamination of polymer films by "bulk surface photograftin g" has been developed. The chemical component of the invention is that the curing of reactive solution between two substrates is initiated by the surf ace free radicals produced by aromatic ketones and surface-hydrogen of subs trates. Using the new approach, two or more polymer films are bonded togeth er by a grafted polymer network which is grafted to adjacent substrate surf aces. The technique has been applied to film substrates of different polyme rs such as polyolefins, polyesters, and polyamides which have abstractable hydrogens at the surface. The photolaminated film composites containing car rier films and an intermediate functional film of low permeability give str ong laminates with high barrier properties, e.g, for oxygen and air.
