PROBLEM TO BE SOLVED: To provide a sheet for a partitioning curtain, which simultaneously satisfies three requirements, i.e., the possible highest transparency, complete shielding against ultraviolet rays in order to protect stored goods, etc., from ultraviolet ray degradation, and provision of an eye-friendly working environment. SOLUTION: The object color of the sheet for the curtain, which is defined according to JIS Z 8722, is in the range of a color having tristimulus values of X=53.57, Y=67.72, and Z=27.24, and having a luminance factor (Y) set to 53.57%, and chromaticities (x) and (y) set to 0.3997 and 0.4253, respectively, which are indicated by coordinate transformation of the tristimulus values, to a color having tristimulus values of X=57.15, Y=70.40, and Z=39.29, and having a luminance factor (Y) set to 70.40%, and chromaticities (x) and (y) set to 0.3797 and 0.3981, respectively, which are indicated by coordinate transformation of the tristimulus values.
