摘要
An ink composition for sensing carbon dioxide gas contains a pH indicator, binder, and solvent and allows easy visual observation of color changes of an indicating portion caused by the concentration of carbon dioxide gas. When this ink composition is applied to a carbon dioxide indicator and package, a pinhole and poor seal of a gas-replaced package sealing a replacement gas which contains carbon dioxide gas are easily found.
