摘要： A sheet of paper is immersed in a reacting solution prepared by dissolving p-n-butoxyaniline, an ultraviolet absorber and polyalcohol in an organic solvent. Then, the organic solvent is allowed to evaporate. Thus, the p-n- butoxyaniline and ultraviolet absorber are spread over the sheet of paper by using the water absorbed in the polyalcohol that serves as a medium for reaction. When the paper is exposed to chlorine or other oxidizing gas, the p-n- butoxyaniline colors, aided by the water absorbed in the, polyalcohol, to form a trace of reaction according to the concentration of the oxidizing gas. Because the ultraviolet absorber prevents the reaction between the p-n-butoxyaniline and light, no discoloration-induced sensitivity drop occurs during storage.

摘要： A coloring indicator, such as metanil yellow, whose color changes in an acidic environment and a polyalcohol, such as glycerin, are applied over a carrier of porous material. The object gas dissolves in the water absorbed in the polyalcohol and reacts quickly with the coloring indicator. As the degree of reaction is proportional to the amount of the gas, differences in the concentration of the object gas can be accommodated by adjusting the exposure time. 19
