Abstract
Ink jettable and UV-curable compositions include a reactive polymer comprising: (a1) at least 20 mol % of recurring units comprising pendant metal complexing water-solubilizing groups, and (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition. The compositions can optionally have a humectant, a dye or pigment colorant, an anionic or nonionic surfactant, a water-soluble or water-dispersible acrylic polymer, or a water-soluble or water-dispersible polyurethane. Such ink jettable and UV-curable compositions can include a complex of reducible metal ions or metal nanoparticles with the reactive polymer.
