<p>Silver halide emulsions can be prepared by precipitating the silver halide grains in the presence of a peptizer comprising a water-soluble starch, said peptizer exhibiting an absorbance of less than 1.0 in the wavelength region 200 to 400nm when measured at a concentration of 2 g/L through a 1 cm transmission path. A useful water-soluble starch having this property is potato starch. Silver halide elements sensitive in the short ultraviolet spectral region can be prepared with these emulsions. <IMAGE></p> |
