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.
Claims14
An article comprising:
- a substrate;
- an aqueous sanitizing solution absorbed into said substrate;
- and
- indicia printed on only a portion of said substrate, said indicia printed with an ink that includes detectable particulate loadings of iron oxide, iron nitrides, or forms of ferritic or martensitic stainless steel in a cured binder, the detectable particulate loadings present in an amount detectable in a single ply of said substrate by an in-line manufacturing production magnetic induction coil metal detector, the detectable particulate loadings being from 1 to 23 total weight percent of said substrate;
- wherein the binder is an acrylic, a polyurethane acrylate, a styrene acrylic copolymer, a butylated melamine formaldehyde resin, or a combination thereof that encapsulates the detectable particulate loadings to inhibit interaction between the indicia and said aqueous sanitizing solution, rendering said ink compatible with storage exposure to said aqueous sanitizing solution absorbed into said substrate.
