Construction: A color imaging material having a substrate and at least one photosensitive layer provided on the substrate, said photosensitive layer comprising, in 100 parts by weight of a binder, 1 to 100 parts by weight of a fulgide compound having photochromic characteristics such that it has an absorption maximum in the region of 430 to 480 nm in color developed condition, 1 to 100 parts by weight of a fulgide compound having photochromic characteristics such that it has an-absorption maximum in the region of 500 to 550 nm in color developed condition, and 1 to 100 parts by weight of a fulgide compound having photochromic characteristics such that it has an absorption maximum in the region of 600 to 650 rim in color developed condition. Technical Effect: A full color image can be obtained by a single time exposure. No other processing, such as development or fixation, is required. Multicolor images obtainable according to the invention have good dark-place storage stability and high image quality. The invention permits a wide range of binder selection. According to the invention, an image material capable of repetitive use is provided.
