ABSTRACT:
The esters are soluble in an aqueous solution of a base before exposure to actinic radiation but, on exposure to actinic radiation, polymerize and become insoluble in such an aqueous solution. Development of photopolymerized images does not therefore require the use of toxic or flammable organic solvents. They contain free carboxyl groups and at least one unit of the formulae I-IV ##STR1## where R.sup.1 is a carbon atom chain containing specified groupings, such as one of formula --CH.dbd.CH--CO--CH.dbd.CH--, --CH.dbd.CHCO--, --COCH.dbd.CHC.sub.6 H.sub.4 CH.dbd.CHCO--, or ##STR2## and Y is oxygen or sulfur. They are obtained by the reaction of an at least dianhydride of a polycarboxylic acid with alcoholic hydroxyl groups of an alcohol containing at least one unit of formula I-IV.
