    摘要： A radiographic screen/film combination or system has 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 380 nm, as e.g. a niobium and gadolinium doped, monoclinic M, yttriumtantalate (MYT) phosphor corresponding to formula IYTaO.sub.4 :Gd:Nb (I),ii) said film comprises {111} tabular silver halide grains rich in silver chloride, spectrally sensitive to irradiation in the said wavelength range shorter than 380 nm by the presence of at least one azacyanine dye as a spectral sensitizer.

    摘要： A method of colour laser marking a security document precursor including at least: a transparent biaxially stretched polyethylene terephthalate foil; at least one colourless colour forming layer for generating a colour different from black containing at least an infrared absorber a colour forming compound and a polymeric binder; and a laser markable polymeric support or a laser markable layer for generating a black colour; comprising the steps of: laser marking the colourless colour forming layer through the transparent polymeric foil with a infrared laser used in continuous wave mode to generate a colour different from black; and laser marking the laser markable polymeric support or the laser markable layer through the transparent polymeric foil with the same infrared laser but used in a pulsed mode to generate a black colour.
