PURPOSE:To reduce the dependency of the subject material due to a gray viewing light source by incorporating jointly compds. (A) capable of affording a pigment to be reduced, which release the pigment having max. absorption separated from each other by more than a prescribed wavelength, respectively, in the photosensitive material. CONSTITUTION:The photosensitive material contains 3 kinds of the compds. (A) capable of affording a pigment to be reduced which release the pigment of the yellow, the magenta and the cyan diffusible pigment capable of being reduced by an electron donating body, respectively. And, the compds. (A) capable of releasing the pigment having the max. absorption separated from each other by >=5nm respectively, are incorporated jointly in one or more among 3 kinds of the compds. (A) having different hues. Thus, as the spectral absorption region of the material is broaden, the dependency of the material due to the gray viewing light source is reduced. And, the compd. (A) is composed of a compd. shown by the formula, etc. In the formula, X is oxygen or sulfur atom, etc., R<101> and R<102> are each a group other than hydrogen atom or a single bond, Time is a group capable of releasing Dye after being released as a group -(Time)t-Dye by reducing it, (t) is 0 or 1, Dye is a pigment (or its precursor). |
