    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.

    摘要： A composition that is photopolymerizable upon absorption of light in the wavelength range from 300 to 450 nm, the composition comprising a binder, a polymerizable compound, a sensitizer and a photoinitiator, characterized in that the sensitizer is an optical brightening agent having a solubility in methyl ethyl ketone of at least 15 g/kg measured at 20° C., allows to produce printing plates without pinhole defects, even if the printing plate precursor is stored before exposure and processing.

    摘要： A process for preparing a photothermographic material with increased photosensitivity, the photothermographic material comprising a support and a photo-addressable thermally developable element, exclusive of a compound R—S(M)n wherein R is an aliphatic hydrocarbon, aryl or heterocyclic group, M is a hydrogen atom, or cation, and letter n is a number determined so as to render the molecule neutral and also exclusive of a compound capable of releasing a mobile dye corresponding to or inversely corresponding to the reduction of silver halide to silver at elevated temperatures, the photo-addressable thermally developable element containing a photosensitive agent in catalytic association with a light-insensitive organic silver salt, a reducing agent for the light-insensitive organic silver salt in thermal working relationship therewith and a binder, comprising the steps of: (i) increasing the photosensitivity of a photosensitive silver halide by chemical sensitisation with a chemical sensitising merocyanine dye containing a thione group in a non-oxidative aqueous medium, optionally in the presence of the light-insensitive organic silver salt, thereby producing the photosensitive agent; (ii) coating the support with one or more aqueous solutions or dispersions together containing the light-insensitive organic silver salt, the photosensitive agent, the reducing agent and the binder; (iii) drying the coating or coatings thereby producing the photo-addressable thermally developable element.
