Abstract

This invention relates to an adhesive composition comprising (a) an acrylic functional urethane elastomer, (b) an acrylic monomer, (c) an organic sulphimide, an organic sulphinate or a salt thereof, (d) a peroxide initiator and (e) a tertiary amine curing accelerator. Component (e) preferably has at least two tertiary nitrogen atoms in its structure and is a reactive organic dye. The adhesive composition is curable aerobically, has faster curing rates than achieved hitherto and shows improved bond-strengths when compared with convetional tertiary amine curing accelerators.
