  • filter dyes are particularly preferred, and dyes absorbing a large amount of light having wavelengths in the range from 350 nm to 480 nm rather than light having wavelengths in the range from 481 nm to 580 nm are used. That is, the dyes to be used in the present invention may be those capable of absorbing a large amount of light with wavelengths in the range as specified above, but some of particularly preferable dyes are mentioned below.

  • the blue light sensitivity relative to the sensitivity of the green light sensitivity of the light-sensitive photographic material which is made as 100 is limited to 45 or less, because graininess cannot be improved if it is higher than 45. Also, if the lower limit of the blue light sensitivity is lower than the above limited value, roughening of image is conspicuous in spite of the large amount of the sensitizing dyes added and graininess cannot be improved.
