ABSTRACT:
A quantitative analysis film comprising a reagent layer comprising a cationic dye-forming color indicator for detecting hydrogen peroxide and an anionic polymer. By the use of such a color indicator and an anionic polymer in combination, a cationic dye is formed; the formed cationic dye is then bound and fixed to the anionic polymer to provide an intensified color. A method for the colorimetric assay of hydrogen peroxide or a precursor thereof with high sensitivity and high efficiency is also disclosed.
