Abstract (en)
A film material has been provided with emulsions comprising ä111ü tabular silver halide grains rich in silver bromide, spectrally sensitive to irradiation in the wavelength range shorter than 420 nm by the presence of at least one blue spectral sensitizer and of at least one azacyanine dye, the formula of which has been given in the description and in the claims. A radiographic screen/film combination or system has also been provided comprising a duplitized film sandwiched between a pair of supporting or self-supporting X-ray intensifying screens, characterized in that i) said pair of supported or self-supporting X-ray intensifying screens essentially consists of luminescent phosphor particles emitting at least 50 % and more preferably at least 80 % of their emitted radiation in the wavelength range shorter than 420 nm, ii) said film corresponds with the film material disclosed hereinbefore.
