摘要： Positive-working imageable elements and methods for their preparation are disclosed. The elements comprise a hydrophilic substrate; a bottom layer, which contains a positive-working photosensitive composition; and a protective overlayer, which has an overlayer material that reduces the solubility of the photosensitive composition in an aqueous alkaline developer. The overlayer may be conveniently applied by a dip and rinse procedure.

摘要： A method for developing exposed lithographic printing plate precursors using a developer and replenisher is disclosed. The replenisher contains a higher concentration of a coating attack-suppressing agent than the developer, so that the aggressiveness of the developer remains substantially constant during the developer loading cycle.
