Abstract

PURPOSE:To easily form a high contrast image by a contact reflection printing method by using a photosensitive material obtd. by laminating a photosensitive diazo layer and a fluorescent dye layer on a support in succession. CONSTITUTION:On a support 1 such as a resin sheet or paper a photosensitive diazo layer 2 having about 1-20mum thickness and a fluorescent dye layer 3 having about 0.5-10mum thickness are laminated to obtain a photosensitive material. The preferred combination of the diazo compound with the fluorescent dye is the combination of 2,5-dibutoxy-4-morpholinobenzene diazonium salt having 405nm maximum wavelength of absorption with bis(triazinylaminostilbene) disulfonate absorbing light of 350-370nm and emitting light of 400-420nm. An original is brought into contact with the layer 3 of said photosensitive material, and after uniformly irradiating the material with ultraviolet light from the support 1 side, the material is developed with alkali to form a color image.
