The present invention relates to a specific compound (A) represented by the following formula (1), a photopolymerizable compound (B), and light, which are used for bonding an optical substrate and an optical substrate having a light-shielding part on the surface. The present invention relates to an ultraviolet curable adhesive containing a polymerization initiator (C), a cured product obtained by irradiating the adhesive with ultraviolet rays, and an optical member such as a touch panel having the cured product. By using the ultraviolet curable adhesive of the present invention, even when a light-shielding portion is formed on an optical substrate such as a transparent protective plate, ultraviolet rays from one direction can be obtained without damaging the liquid crystal display device or the like. By irradiation, the adhesive located in the light shielding region that is shielded from light by the presence of the light shielding part can be sufficiently cured. |
