Abstract
An indicator for the detection of hydrogen peroxide. It undergoes a color change according to the concentration of hydrogen peroxide and this color change can be visually recognized with higher certainty. An ink composition for hydrogen peroxide detection is provided which comprises 1) at least one of styrene-acrylic resins and styrene-maleic acid resins and 2) a methine dye. A color change layer formed from the ink composition for hydrogen peroxide detection produces an effect that a color change according to, e.g., the concentration of hydrogen peroxide can be visually recognized.
