DRY LITHOGRAPHIC FORME

摘要

A dry lithographic forme comprising a support and, stacked thereon in the following order, a photosensitive layer and a silicone rubber layer, wherein the photosensitive layer contains either a reaction product formed between a compound having at least one phenolic hydroxyl group and at least one non-phenolic hydroxyl group and a quinone diazide compound, or both of a reaction product formed between a compound having at least one phenolic hydroxyl group and a quinone diazide compound and another reaction product formed between a compound having at least one non-phenolic hydroxyl group and a quinone diazide compound. The forme has such excellent image reproductivity and plate wear that it is suitable for use in commercial and newspaper offset rotary presses wherein a high plate wear is required, thus being economically advantageous.
