摘要:
A water-developable lithographic printing plate material is described comprising a support characterised by comprising on the support a photosensitive layer containing an oil-soluble diazo resin and a non-photosensitive resin having a moisture sorption ratio from 5 to 20% at 80% relative humidity.
摘要:
A silver halide photographic light sensitive material is disclosed, comprising a support having thereon a silver halide emulsion layer comprising a silver halide emulsion, wherein the silver halide emulsion comprises silver halide grains having an average iodide content of 0 to 1 mol%, at least 50% of total grain projected area is accounted for by tabular grains having an aspect ratio of 2 to 20; and the silver halide grains being spectrally sensitized with a sensitizing dye represented by the following formula (1) or (2):
摘要:
A developer composition of an alkaline aqueous solution containing a reducing inorganic salt, typically an alkali metal salt of sulfurous acid such as sodium sulfite, is disclosed for development of a lithographic printing plate material containing a photosensitive o-quinonediazide compound and an organic polymer, with reduced deterioration in developing capacity caused by the air, and with enhanced stability with time. In particular, a developer composition composed of an alkaline aqueous solution of pH 11 or higher containing a water-soluble sulfurous acid salt is effective for developing both of a lithographic printing plate material having a nega-type photosensitive layer containing a photosensitive diazo compound and an organic polymer, and a lithographic printing plate material having a posi-type photosensitive layer containing an o-quinonediazide compound and an organic polymer.
