Abstract: An article is provided having a substrate with an indicia printed on the substrate, where the indicia is printed with an ink that is detectable by in-line manufacturing production X-ray, metal, or magnetic detectors. A package for multiple such articles is also provided. A process for detecting a sanitizable substrate wipe with magnetic, metal, or X-ray detection equipment in a production setting is also provided. With process implementation article loss in a product can be detected thereby reducing precautionary product discard.

Abstract: A reversible color-changing polymeric article includes a polymeric material and a dried reversible color-changing ink formulation durably bound to the polymeric material. During use, the polymeric article is impregnated with a sanitizer solution that contains a quaternary ammonium compound. The polymeric article reversibly changes between a first color when impregnated with the sanitizer solution and a second color when the sanitizer solution is depleted during use.

Abstract: A reversible color-changing ink formulation, and a nonwoven wipe to which the ink formulation is securely bound, are provided. The reversible color-changing ink formulation includes about 55-98% by weight of a polymer binder, about 0.1-20% by weight of a reversible color-changing dye that reversibly changes between a first color and a second color at a pH of about 5.5 to about 8.0, and optional amounts of plasticizer, inorganic particulate filler, and color brightener. During use, the nonwoven wipe is impregnated with a sanitizer solution that contains a quaternary ammonium compound. The nonwoven wipe reversibly changes between a first color when impregnated with the sanitizer solution and a second color when the sanitizer solution is depleted during use. The change to the second color indicates the need to recharge the nonwoven wipe with the sanitizer solution, whereupon the first color returns.
