<p>A one-component air-activatable polymerisable adhesive composition comprising: (a) a free-radically polymerisable monomer, and an activator system for effective polymerisation of the free-radically polymerisable monomer, said activator system comprising: (b) an autoxidisable compound which is a dihydropyridine (other than a stabilised 1,4-dihydropyridine) (c) an onium salt selected from diazonium, iodonium and sulfonium salts which do not interfere with polymerisation, and (d) a soluble ionic salt, with the proviso that the composition does not contain a peroxide, or a peroxide precursor which produces peroxide in the absence of air or any ingredient which is a significant source of radicals in the absence of air. Exemplary onium salts are diaryl iodonium, triarylsulfonium and aryl diazonium salts.</p> |
