An optical adhesive product and a process for manufacturing an optical adhesive product, laminated film ensembles, and laminated lenses. The optical adhesive product includes a glyoxal water solution that is pH adjusted for use as an optical adhesive that demonstrates a wet peel force strength above about 6 Newtons. A water based polymer, such as PVOH, may be added to the adhesive system. According to the process, the glyoxal adhesive system is manufactured and utilized to laminate TAC-PVA-TAC films together to form a polar film ensemble. The polar film ensemble is laminated to an optical substrate and in the case of an ophthalmic lens, surfaced, coated and edged. The optical adhesive product avoids film separation in the polar TAC-PAV-TAC film ensemble during edging.

A binder includes a polyethyleneimine salt and a carboxylate salt polymer. The binder of this application can effectively release stress and maintain the integrity of a molecular network during expansion of particles of a negative active material, thereby exhibiting advantages of both high strength and high toughness, effectively reducing disruption of a bonding interface, and improving cycle performance of the electrochemical device.
