The adhesive precursor comprises a polyhydric alcohol, a non-ionic unsaturated free radically polymerizable material, a free radical initiator, a crosslinking agent and an ionizable salt. The adhesive precursor is polymerized after coating onto the electrode plate or releasable transfer sheet, preferably by exposure to ultraviolet radiation.Other References
