Title:
CHROMOGENIC REACTION COMPOSITION, CHROMOGENIC REACTION FILM, AND METHOD FOR SUPPRESSING COLOR FADING
Document Type and Number:
WIPO Patent Application WO/2021/039708
Kind Code:
A1
Abstract:
The purpose of this invention is to improve the storage stability of a metal ion detection reagent. A chromogenic reaction composition according to this invention comprises a metal ion detection reagent and a radical scavenger. A chromogenic reaction film according to this invention comprises, on the surface thereof, a metal ion detection reagent that is present in the form of fine particles that carry a radical scavenger. Further, a method for suppressing color fading of a metal ion detection reagent according to this invention comprises a step for capturing radicals in a chromogenic reaction composition comprising the metal ion detection reagent.
