An oxygen sensing composition (1) comprising a complex in which a cationic surfactant, a reversible color-changing organic dye and a reducing agent are inserted between layers of a layered silicate, and a reversible color-changing organic dye and a reducing agent An oxygen detector formed by applying or printing an oxygen detection composition (2) comprising a mixture on a substrate. [Effect] It excels in light resistance and storage stability, and is excellent in response to a decrease in oxygen concentration. [Selection figure] None. |
