  • Patent number: 10640663
    Abstract: The present invention relates to a ceramic printing ink composition having antibacterial function, and more particularly to a ceramic printing ink composition which is prepared by mixing deionized water, propylene glycol, propylene glycol methyl ether acetate (PMA) solvent, propylene glycol methyl ether (PM) solvent, isopropyl alcohol (IPA), a dispersing agent, a pigment. In a process of printing a pattern using the ceramic printing ink composition, the pattern is printed between or on ceramic coating layers by pad, screen or stamp printing. More specifically, ceramic coating (sol-gel) layers (1-coat, 2-coat, 3-coat, etc.) are formed and set-to-touch, after which the ceramic printing ink composition is coated on the coating layer and heated and cured simultaneously with the coating layers. Thus, bonding and adhesive strength of the ceramic printing ink composition is enhanced to enable printing to be more stably and easily performed on the ceramic coating layer.
