Abstract

Novel, improved adhesive compositions curable at ambient temperature to form adhesive bonds between opaque, impervious, substrates without external application of heat, light or other radiation. The adhesive compositions of this invention comprise one or more ethylenically unsaturated monomers, a source of free radicals, and an activator comprising an azine dye material or the reaction product of an azine dye material with a reducing agent.
