Abstract
The present invention relates to a silver halide photographic emulsion and particularly to a silver halide photographic emulsion spectrally sensitized for argon laser beam exposure having an improved high spectral sensitivity to flash exposure using flash rays having main emission peaks at wave lengths of 514.5 nm, 488.0 nm and 476.5 nm (argon laser rays).
