<P>PROBLEM TO BE SOLVED: To provide a photocuring adhesive composition for optical use that is favorably used particularly as a photocuring adhesive used for bonding optical articles such as lenses and prisms, and has a high refractive index, good curability, and strong adhesive strength by including a specific mercapto compound, a photo-polymerization initiator, and a silane coupling agent in the adhesive. <P>SOLUTION: The adhesive is mainly constituted of a photocuring adhesive composition containing a mercapto compound having at least ≥2 thiol end groups, a compound having ≥2 unsaturated bonds, a photo-polymerization initiator, and a silane coupling agent. <P>COPYRIGHT: (C)2003,JPO |
