Provided is a light-blocking film capable of efficiently blocking ultraviolet radiation in a long wavelength region of 380 nm to 400 nm with the use of a small amount of an ultraviolet absorber added thereto. The light-blocking film is characterized by comprising at least one triazine compound represented by the following Formula (1) as an ultraviolet absorber or having the triazine compound coated thereon:
(wherein, R 1 to R 3 may be the same or different and each represent a linear or branched alkyl group having 1 to 12 carbon atoms or the like, with a proviso that the alkyl group and the like are optionally substituted with a hydroxy group or the like and optionally interrupted by an oxygen atom, a sulfur atom, a carbonyl group, an ester group, an amide group or an imino group, the substitution and interruption optionally existing in combination; and R 4 to R 6 may be the same or different and each represent an alkyl group having 1 to 8 carbon atoms or an alkenyl group having 2 to 8 carbon atoms). |
