Abstract
"Release on demand" pressure-sensitive adhesives and tapes which are readily detackifiable by exposure to actinic radiation. The adhesive system has an oxirane ring-bearing component blended thereinto (or preferably reacted therewith) to achieve an adhesive epoxy equivalent value of 400-900, preferably 450-700. The adhesive system also includes an effective amount of ionic photoinitiator capable of promoting the polymerization of oxirane rings.
