Abstract
A photographic product having an exposure function is described, which has therein a built-in color photographic material comprising a support having provided thereon at least one red-sensitive emulsion layer, at least one green-sensitive emulsion layer and at least one blue-sensitive emulsion layer and having a specific photographic sensitivity of 640 or more, wherein the built-in color photographic material is characterized by blue, green and red density function curves D (logE) in which in each curve a region defined by a gamma (<.gamma.>=dD/dlogE) of 0.4 or more is 2.8 or more as logE.
Claims4
A photographic product having an exposure function, which has therein a built-in color photographic material comprising a support having provided thereon at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer and having a specific photographic sensitivity of 640 or more, wherein the built-in color photographic material is characterized by blue, green and red density function curves D (logE) in which in each curve a region defined by a gamma (<.gamma.>=dD/dlogE) of 0.4 or more has a logE of 2.8 or more,
- wherein interlayer effects are present in the built-in color photographic material in the following magnitude IE (X/Y):
- 0.15<IE (R/G),
- -0.05<IE (R/B),
- 0.10<IE (G/R),
- 0.15<IE (G/B),
- 0.03<IE (B/G), and
- 0.15<IE (B/R),
- wherein IE (X/Y) indicates the magnitude of the interlayer effect from a color-sensitive layer x to a color-sensitive layer Y, and G, B and R indicate a green-sensitive layer, a blue-sensitive layer and a red-sensitive layer, respectively, wherein all the at least one red-sensitive layer and all the at least one green-sensitive layer have silver halide emulsions having a mean AgI content of from 2 to 5 mol %.
