<p>The present invention is directed to sulfonium salt-containing compounds represented by a following general formula; <CHEM> wherein R1 is alkyl containing from 1 to 18 carbon atoms, hydroxy, alkoxy containing from 1 to 18 carbon atoms, alkylcarbonyloxy containing from 1 to 18 carbon atoms or halogen, n is any of 0, 1, 2 or 3, however, each of R1 may be different from the others when n is 2 or more, R2 is alkyl containing from 1 to 6 carbon atoms, R3 and R4 are each independently hydrogen or alkyl containing from 1 to 6 carbon atoms, R5 and R6 are each independently hydrogen, alkyl containing from 1 to 6 carbon atoms, hydroxy, alkoxy containing from 1 to 6 carbon atoms, alkylcarbonyloxy containing from 1 to 18 carbon atoms or aromatic carbonyloxy, and R7 is alkyl containing from 4 to 20 carbon atoms or a group represented by a following formula; <CHEM> wherein R8 is alkyl containing from 1 to 18 carbon atoms, hydroxy, alkoxy containing from 1 to 18 carbon atoms, alkylcarbonyloxy containing from 1 to 18 carbon atoms, aromatic carbonyloxy or halogen, m is any of 0, 1, 2 or 3, however, each of R8 may be different from the others if m is 2 or more, and X is non-nucleophilic anion residue, and hardening compositions comprising said sulfonium salt-containing compounds. In particular, a hardening composition comprising the sulfonium salt-containing compound represented by the general formula ÄIÜ shown above, a sensitizer and a cationic polymerizable compound can harden in a short time under either heating or irradiation of light or the like, and therefore, said hardening composition can be suitably used for coating materials, adhesives, photoresists, etc.</p> |
