Inkjet‐printable aqueous suspensions of conjugated polymer precursors are developed for fabrication of patterned color images on paper substrates . Printing of a diacetylene (DA)‐surfactant composite ink on unmodified paper and photopaper, as well as on a banknote, enables generation of latent images that are transformed to blue‐colored polydiacetylene (PDA) structures by UV irradiation. Both irreversible and reversible thermochromism with the PDA printed images are demonstrated and applied to flexible and disposable sensors and to displays.
