The invention describes a method of curing a polymerizable material containing ethylenically unsaturated bonds at a temperature of 60° C. or less, comprising the steps of (a) providing a curative comprising an effective amount of a light-stable isomer of a 2,4,5-triarylimidazolyl dimer, such as bilophine; (b) activating said curative by application of an activator selected from the group consisting of solvent and friction; and (c) combining the activated curative with the polymerizable material. Articles comprising an adhesive having a detackified surface, such as adhesive bandages, a detackifying solution, a two-part adhesive system, and a fastening system are also provided.
