Abstract

A silver halide photosensitive material is subject to J-band spectral sensitization in the infrared range such that it has a sensitization maximum at a longer wavelength than 730 nm and the sensitivity at the spectral sensitivity maximum wavelength is higher by a factor of at least 4.5 than the spectral sensitivity to light having a wavelength 30 nm longer than said spectral sensitivity maximum wavelength and higher by a factor of at least 2 than the spectral sensitivity to light having a wavelength 30 nm shorter than said spectral sensitivity maximum wavelength. The photosensitive material has high sensitivity to light in a specific wavelength range such as semiconductor laser light, but low sensitivity to light in other wavelength ranges and experiences a minimal lowering of sensitivity during storage.
