Abstract

PURPOSE: An oxygen sensing agent, making it possible to recognize the presence of oxygen with the naked eye by observing change of color tone, which contains a specified compound as a color developing agent.
CONSTITUTION: An oxygen sensing agent is prepared by mixing (A) about 0.001W 1wt% of a compound (e.g., formula II) of formula I (wherein R1WR8 are H, methyl, chlorine or ethoxy), (B) glucose, (C) at least one selected from a hydroxide and a silicate of an alkali (or alkaline earth) metal, and (D) about 0.1W20wt% of at least one selected from water, an alcohol and a glycol (in a weight ratio of the component (B) to (A) of about 5W1,000, and of the component (C) to (B) of about 0.1W1,000). Said sensing agent reversibly turns yellow-yellowish white in the absence of oxygen and violet in the presence of oxygen.
