PROBLEM TO BE SOLVED: To provide an ultraviolet sensitive sheet, an ultraviolet sensitive set, and an ultraviolet sensitive method, capable of achieving a continuous color development according to an integral illumination of ultraviolet rays, simple in measurement of an ultraviolet irradiation amount in a wide area, excellent in ultraviolet irradiation amount measurement in a range of 1 mJ/cmto 1,000 mJ/cm, and adjusting the ultraviolet irradiation amount which contributes to the color development.SOLUTION: An ultraviolet sensitive sheet includes a support body and an ultraviolet sensitive layer in this order. The ultraviolet sensitive layer has a capsule including a photo-oxidant and a leuco dye capable of carrying out an oxidation-color-development by the photo-oxidant. The ultraviolet sensitive sheet includes: an ultraviolet sensitive layer containing sheet in which a mass ratio of the photo-oxidant to the leuco dye is 0.2 to 1.0:1 and an amount of the leuco dye per surface area 1 mof the ultraviolet sensitive layer is 0.1 to 1.0 g; and an ultraviolet sensitivity adjusting film. |
