ABSTRACT:
An absorbent pad configured for placement under a patient to absorb bodily fluids includes a liquid permeable cover layer, a liquid impermeable back sheet, and an absorbent structure disposed between the cover layer and the back sheet. At least one of the cover layer, back sheet, or absorbent structure incorporates a dried application of a liquid activated carbon ink having activated carbon, a binder, and a solvent, with the dried application of ink having a solids add-on level of at least about 2%. The activated carbon ink is applied in a pattern over between about 25% to about 95% of a total upper surface area of the pad and presents a visually contrasting color against a background color of the pad or a contrasting ink.
