  • Patent number: 4717605
    Abstract: Radiation curable adhesives which are based on ionically polymerizable epoxide systems and ionic photoinitiators of the triarylsulfonium complex salt type additionally also contain at least one ethylenically unsaturated substance which can be polymerized by free radicals and at least one free radical photoinitiator. These exhibit particular advantages in the gluing of optical glass components. The gluing can be partially hardened with UV radiation until fixing of the glass components is achieved. In this partially hardened state, the components can be adjusted. Complete hardening is then carried out with UV radiation.
