NEW TRIAZINE DERIVATIVE, ULTRAVIOLET ABSORBER, AND RESIN COMPOSITION

-

Page/Page column 36-37, (2012/06/18)

To provide a novel triazine-based compound exhibiting an ultraviolet blocking effect even in the long-wavelength region and being useful as an ultraviolet absorber with excellent light resistance, and to provide an ultraviolet absorber and a resin composition, which can maintain a long-wavelength ultraviolet-blocking effect for a long period of time. A compound represented by the following formula (1): wherein each of R1a, R1b, R1c, R1d and R1e independently represents a hydrogen atom or a monovalent substituent excluding OH, provided that at least one substituent represents a substituent having a Hammett's σp value of 0.3 or more and substituents may combine with each other to form a ring, and each of R1g, R1h, R1i, R1j, R1k, R1m, R1n and R1p independently represents a hydrogen atom or a monovalent substituent, provided that substituents may combine with each other to form a ring.
