PURPOSE:To permit exact color reproduction independently of the kinds of originals by using a green sensitive sensitizing dye having <=544nm wavelength of spectral sensitivity. CONSTITUTION:This material has a layer contg. an internal latent image type silver halide emulsion which is not previously fogged and the compd. expressed by formula I on a base. In the compd. expressed by formula I, R3 is the substituent having such values of LL and B at which the value of S expressed by formula II is <=544. In formula I, R0, R1 is a hydrogen atom, alkyl group R2 is hydrogen atom, alkyl group or aryl group; R3 is an alkyl group of >=2C, aryl group, alkoxy group of >=2C, aryloxy group, etc.; R4, R6 are an alkyl group; (n) is 0 or 1. Copies having the excellent color reproducibility are thereby obtd. even if the kinds of the originals vary. |
