Abstract
A novel compound having the formula: ##STR1## wherein: R is alkyl containing from 1 to 10 carbon atoms; and PA0 M is a monovalent cation, selected from the group consisting of alkali metal and ammonium, has been synthesized in high yield by hydrogenating the corresponding arylsulfonate in a solvent which simultaneously prevents hydration of the sulfonate group and hydrolysis of the ester functions. The compound is useful in preparing condensation polymers having ionic groups. In particular, these condensation polymers comprise additional polymerized copolymerizable dicarboxylic acids and diols, diamines or hydroxyamines, to yield polyesterionomers useful in dye imbibition photohardenable imaging materials for forming positive dye images.
