摘要：A period indicator including a liquid-permeable substrate and an indicativesection which is overlaid on a portion of the substrate and which is formed from a liquid-permeable material having a low light refractive index, the indicator containing a volatileliquid, wherein the indicative section is formed by coating a surface of the substrate withan indicative-section-forming material prepared by mixing a binder and finely dividedparticulate matter having a low light refractive index, the indicative section is composed
of two or more regions, and the regions differ in height from one another as measuredfrom the surface of the substrate, as the coating amounts per unit area of the indicativesection forming material in respective regions differ from one another. Since the periodindicator can indicate the chemical-containing state stepwise, it is useful for indicating theavailable period of use of a chemical such as a mothproofing agent, an insecticide, adeodorant, or a fragrance.
