Abstract
Flexographic printing members are prepared by developing an exposed flexographic printing member precursor with an aqueous flexographic developer. The aqueous flexographic developer comprises: a) a fatty acid composition consisting of one or more saturated or unsaturated fatty acids or alkali metal salts thereof, each saturated or unsaturated fatty acid or alkali metal salt thereof independently having 12 to 20 carbon atoms, the fatty acid composition being present in an amount of 0.25-2.0 weight %, and at least 85 weight % of the fatty acid composition is composed of one or more C18 mono- or poly-unsaturated fatty acids or alkali metal salts thereof; b) an aminopolycarboxylic acid or alkali metal salt thereof in an amount of 0.05-0.30 weight %; c) a buffer compound in an amount of 05-0.60 weight %; and d) water. Such aqueous flexographic developers can also be provided in concentrated form and appropriately diluted before or during use.
