Colorimetric moisture-indicating compositions comprising a modified moisture-indicating composition comprising (a) a moisture-indicating composition comprising (1) a solid support and (2) a bis(glyoxime)-transition metal complex bound to the solid support, and (b) a modifier comprising at least one hygroscopic salt are described. In some embodiments, the at least one hygroscopic salt is in physical contact with or in fluid communication with the moisture-indicating composition and comprises an anion the group comprising halide, nitrate, acetate, carbonate, and hydroxide; and a cation selected from the group comprising ammonium, an alkali metal, an alkaline earth metal, and a transition metal. These colorimetric moisture-indicating compositions can be used to make a colorimetric relative humidity-indicating sensor. A method of adjusting the colorimetric response of a colorimetric moisture-indicating composition and a method of detecting moisture are also provided. Colorimetric moisture indicating cards comprising the colorimetric moisture-indicating compositions are also provided. |
