    摘要： A cost efficient method of making a lithographic printing plate precursor is disclosed, the method comprising the steps of coating a silver halide emulsion layer on a hydrophilic base which is provided with physical development nuclei; simultaneously with the preceding step, coating on the emulsion layer a solution that induces silver salt diffusion transfer reversal development of the silver halide; allowing diffusion of complexed silver ions to the physical development nuclei, thereby forming silver metal that is deposited on the hydrophilic base; a wash-off step wherein the emulsion layer is removed from the silver metal. The material thus obtained can be exposed image-wise in heat-mode, e.g. by means of an infrared laser, thereby ablating the silver metal and revealing the hydrophilic base at exposed areas. Immediately after exposure, it can be used as a lithographic printing plate without the need for a wet processing step.

    摘要： A heat-sensitive composition can be used to make a heat-sensitive imaging material. The composition includes a water-soluble or water-dispersible binder and dispersed therein, a photothermal conversion material, and hybrid particles of a combustible nitro-resin and an addition polymer derived from one or more ethylenically unsaturated polymerizable monomers. The hybrid particles preferably have a core-shell structure with the combustible nitro-resin comprising the core and the addition polymer providing the shell. These imaging materials are particularly useful as nulldirect-writenull thermally imageable elements useful to provide lithographic printing plates without ablation or the need for alkaline development.
