AQUEOUS PIGMENT INK FOR TEXTILE INKJET PRINTING, AND METHOD FOR PRODUCING PRINTED TEXTILE ITEM
20230416545 · 2023-12-28 ·

Provided is an aqueous pigment ink for textile inkjet printing, including a pigment, a water-dispersible resin, water, and a water-soluble organic solvent, wherein an ink film made by drying the aqueous pigment ink for textile inkjet printing has a weight change ratio of 20% or less between before and after immersion in warm water at 50 C., and has a film elongation of 50% to 300% after immersion in warm water at 50 C. Also provided is a method for producing a printed textile item.

FORMATION OF ELECTRICALLY CONDUCTIVE LAYERS AT ROOM TEMPERATURE USING SILVER NANOPARTICULATE PROCESSING AND INKS FOR FORMING THE LAYERS

Room temperature processing has successfully resulted in highly conductive coatings formed from silver nanowires with a cellulose binder. The conductive coatings can be formed with silver salts to fuse the silver nanowires into a unitary fused metal nanostructured network. Even without added silver salts, low sheet resistance values can be obtained. Room temperature processing can be effective over a range of transmittance values from highly transparent to modestly transparent to translucent to opaque. The ability to form the transparent coatings opens the processing to a wide range of substrates that are not processible with higher process temperatures.
