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., resorufin) having an oxazine skeletone of the formula [wherein X is an oxygen atom or N+(CH3)2], (B) glucose, (C) at least one selected from a kydroxide, a silicate of an alkali (or alkaline earth) metal, and aluminum hydroxide, 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 5W 1,000 and of the component C to B of about 0.1W1,000). Said oxygen sensing agent reversibly turns yellow-yellowish white in the absence of oxygen and violet in the presence of oxygen.
