METHOD FOR FORMING DIRECT POSITIVE COLOR IMAGE

PURPOSE:To restrain a reversal image from being again reversed and to enhance a direct positive color image in quality by scanning a direct positive color photosensitive material containing a specified compound to expose it to a light from a visible ligh source. CONSTITUTION:The direct positive color photosensitive material having a nonprefogged internal latent image type core/shell type emulsion layer is exposed to the blue-, green-, and red-colors by scanning, and then subjected to development processing to form a color image. At that time, the photosensitive material to be used contains the compound represented by formula I and/or II in which X is an atomic group necessary to form the 5- or 6-membered hetero ring; M1 is H or a mercapto-protecting group; Y is a bonding group; R is alkylene, arylene, or the like; Z1 is a polar substituent; R' is H or a substituent; (n) is 0 or 1; (m) is 0, 1, or 2; each of Z2 and Q is an atomic group necessary to form a desired ring or nucleus; each of R21, R22, Y21, and Y22 is H, alkyl, or the like; (p) is 0 or 1; and (q) is 0, 1, or 2.
