Abstract
The present disclosure describes a method to modify dried polymer films using printed crosslinking agents, including that the crosslinked polymer resulting from the method exhibits greater insolubility compared to crosslinked polymers made where the crosslinking agent and the polymer are combined and applied as a homogenous solution. Articles of manufacture generated by such a method are also disclosed.
