  • Ink composition for sensing carbon dioxide gas, carbon dioxide indicator using the same, package provided with the carbon dioxide indicator, and method for sensing pinhole using the same
    Publication number: 20100224508
    Abstract: An ink composition for sensing carbon dioxide gas contains a pH indicator formed using a combination of two or more types of pH indicator components, binder, and solvent and allows easy visual observation of color changes of an indicating portion caused by the concentration of carbon dioxide gas. When the ink composition is applied to a carbon dioxide indicator and package, a pinhole and poor seal of a carbon-dioxide-ambient package are easily found.
