Claim:
1. A photocurable thiosulfate-containing polymer that has a T g of at least 50° C. and comprises: (a) recurring units comprising pendant thiosulfate groups, and (d) recurring units, wherein the photocurable thiosulfate-containing polymer has sensitivity to irradiation at a wavelength of from 150 nm to 700 nm to cause the pendant thiosulfate groups to form disulfide bonds, which (a) recurring units are represented by Structure (II) below, and the (d) recurring units are represented by Structure (V) below: wherein R represents an organic polymer backbone, G is a single bond or divalent linking group, Q + is an organic charge balancing cation, and “a” represents at least 0.5 mol % and up to and including 99.5 mol % of (a) recurring units, based on the total recurring units in the photocurable thiosulfate-containing polymer; wherein R″ represents an organic polymer backbone, G″ is a carbonyloxy group, R 3 comprises a monovalent linear, branched, or carbocyclic non-aromatic hydrocarbon group having 1 to 18 carbon atoms, or R 3 comprises a phenyl group having one or more linear, branched, or carbocyclic non-aromatic hydrocarbon substituents, at least one of which linear, branched, or carbocyclic non-aromatic hydrocarbon substituent has at least 6 carbon atoms and up to and including 18 carbon atoms, and “d” represents at least 0.5 mol % and up to and including 99.5 mol % of (d) recurring units, based on the total recurring units in the photocurable thiosulfate-containing polymer.
