Abstract

PURPOSE:To obtain the time indicator whose color changes upon contacting with air with the elapse of time by putting variable coloring matter and alkali matter in a base material together. CONSTITUTION:In the non-porous or porous base material having alkali resisting property, variable coloring matter such as P-nitrophenol, Pinachrome, gamma-sultone, indo-oxine, azolitmin, neutral red, night blue, phenolsulfonephthalein, m-nitrophenol, quinoline blue, o-cresol benzene, cresol red, alpha-naphtolphthalein, m-cresol purple, Tropaelin, p-cresol phthalein, p-xylenol blue, thymolsulphonephthalein, 3,3 bis(P-hydroxyphenyl) phthalide, and o-cresol phthalein, and the alkali material such as sodium hydrooxide coexist together. The time indicator prepared in this way discolors when it is contacted with air.
