The present invention provides processes by which a polymeric hydrogel can be securely adhered to a substrate to form a hydrogel laminate with greatly improved delamination resistance. The laminate is formed by casting onto a polymeric adhesive-coated substrate an aqueous solution of hydrophilic polymer, then exposing this composite to ionizing radiation which cross-links the hydrophilic polymer to form a hydrogel and also induces copolymerization of the hydrophilic polymer and the adhesive polymer.
