Summary: | A silver dispersion is obtained by reducing a silver compound in the presence of a polymeric dispersant of an ionic hydrophilic segments, such as methacrylic acid segments con and nonionic hydrophilic segments such as hydroxyl terminated polyethylene glycol segments. Aqueous inkjet inks may contain such dispersants and other common ingredients such as a humectant. The inks can be printed on ceramic substrates and sintered under heat to form solid, conductive patterns of silver. |
