ABSTRACT:
The present invention relates to an ultraviolet absorber for synthetic resins composed of a triazine compound represented by the general formula (I) shown below(wherein R represents an alkyl group having 1 to 4 carbon atoms, n is 0 or an integer of up to 2, and X represents a group selected from the consisting of group (a) to (d) shown below)(wherein R1represents an aliphatic group having 5 to 60 carbon atoms, which is an alicyclic group, an alkyl group having an alicyclic group at the terminal or in the chain thereof, an alkyl group having a branch, or a linear alkyl group, depending on the number of carbon atoms; R2represents an alkyl group having 1 to 18 carbon atoms or a (poly)alkyleneoxyalkyl group; R′ represents an aliphatic diyl group having 5 to 60 carbon atoms; R and n have the same meanings as those described in the general formula (I) above).
