Electro-optic assemblies and related materials (e.g., adhesive) for use therein are generally provided. The electro-optic assembly comprises a hybrid adhesive layer comprising two or more adhesive materials including a polyurethane adhesive material and a polyacrylate adhesive material. The polyurethane adhesive material includes an end-capping cyclic carbonate. In some embodiments, the adhesive layer is formed by curing the two adhesive materials under two different sets of conditions, comprising two or more curing steps.
