Abstract: Provided are: a novel nucleating agent capable of imparting excellent transparency to synthetic resins; a synthetic resin composition containing the same; and a molded object of the synthetic resin composition. The nucleating agent contains at least one triazine compound represented by Formula (1), wherein Ar1, Ar2 and Ar3 each independently represent an unsubstituted phenyl group or a substituted phenyl group. In Formula (1), for example, the number of substituents of the substituted phenyl group is preferably 1, and Ar1, Ar2 and Ar3 are preferably all different groups.

Abstract: Provided is an ultraviolet absorbing agent that efficiently absorbs ultraviolet rays in a wide wavelength region, and in particular, has a strong absorbability in the UV-A region. Also, a synthetic resin composition having excellent weatherability is provided. Provided is an ultraviolet absorbing agent including a triazine-based compound represented by Formula (1) below. Also, a synthetic resin composition containing the ultraviolet absorbing agent is provided. R2, R3, and R4 in the triazine-based compound represented by Formula (1) below are each preferably a hydrogen atom or a methyl group, and particularly preferably a hydrogen atom.
