A resin composition containing a cyanoacrylate ultraviolet ray-absorber (a) represented by the general formula (1), wherein R is an aryl group, R' is an organic group having 1 to 12 carbon atoms, and x is 1 or 2, and benzotriazole ultraviolet ray-absorber represented by the general formula (2), wherein Z, Z' and Z'' are organic groups having 1 to 20 carbon atoms, and m, p, q and s are 0 or 1. The resin composition possesses light resistance of a satisfactory level even when it is used in the applications of optical lenses, developing yellow color little even after used for extended periods of time.
