Abstract
Silver-containing compositions contain a water-soluble complex of a reactive polymer with either reducible silver ions or silver nanoparticles, the reactive polymer comprising: (a) greater than 1 mol % of recurring units comprising sulfonic acid or sulfonate groups, (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition, and optionally (c) at least 1 mol % of recurring units comprising a pendant amide, hydroxyl, lactam, phosphonic acid, or carboxylic acid group, all amounts based on the total recurring units in the reactive polymer. Other silver-containing compositions contain a water-insoluble complex of a reacted polymer with either reducible silver ions or silver nanoparticles. The reacted polymers are derived from the reactive polymers.
