The present invention provides a light-hardening type light-transparent adhesive and adhesive composition, which contains an aliphatic urethane acrylate and a polythiol chain transfer agent. It has excellent reliability in optical properties and environmental resistance such as high temperature, high temperature, high humidity, and ultraviolet rays. It also does not cause contamination when it is hardened between layers such as recoating and the formation of partitions. It has excellent engineering properties, so it is used in the manufacture of adhesives for touch panels. , Then the film is useful. The light-curing light-transparent and adhesive composition of the present invention comprises an aliphatic urethane acrylate, a polythiol chain transfer agent, a monofunctional vinyl monomer, a photopolymerization initiator, and a stabilizer. . |
