Abstract
Indicating panels adapted to provide a qualitative or quantitative indication of a characteristic of a liquid absorbed by the indicator panel. The indicating panels include a porous inner sheet that is impregnated with a first indicator selected to respond to a target analyte by creating a detectable response, and a porous outer sheet impregnated with a polymeric mordant selected to stabilize indicators.

An indicating panel for an incontinence product, comprising:
- a porous inner sheet that is impregnated with a first indicator;
- wherein the first indicator is selected to respond to a target analyte by creating a detectable response;
- a porous outer sheet adjacent to the inner sheet, wherein the outer sheet is impregnated with a polymeric mordant selected to stabilize indicators that generate detectable responses;
- and
- a separation layer disposed between the inner sheet and the outer sheet, wherein the separation layer is at least water-soluble.
An indicating incontinence product, comprising:
- an absorbent core;
- a porous inner sheet adjacent to the absorbent core that is impregnated with a first indicator;
- wherein the first indicator is selected to respond to a target analyte by creating a detectable response;
- a porous outer sheet adjacent to the inner sheet, wherein the outer sheet is impregnated with a polymeric mordant selected to stabilize indicators that generate detectable responses;
- and
- a separation layer disposed between the inner sheet and the outer sheet, wherein the separation layer is at least one of water-soluble and porous.
An indicating system for an incontinence product, comprising:
- an indicating panel including:
- a porous inner sheet impregnated with a pair of coupled indicators,
- wherein a first indicator of the coupled pair is selected to respond to a target analyte by creating a reporting condition,
- wherein a second indicator of the coupled pair is selected configured to respond to the reporting condition by generating a detectable response,
- a porous outer sheet adjacent to the inner sheet, wherein the outer sheet is impregnated with a polymeric mordant selected to irreversibly stabilize the second indicator that is generating the detectable response, and
- a separation layer disposed between the inner sheet and the outer sheet, wherein the separation layer is at least one of water-soluble and porous;
- and
- a reference panel disposed adjacent to the indicating panel, where the reference panel includes a substantially white and porous material.
An indicating panel for an incontinence product, comprising:
- a porous inner sheet that is impregnated with a first indicator;
- wherein the first indicator is selected to respond to a target analyte by creating a detectable response;
- a porous outer sheet adjacent to the inner sheet, wherein the outer sheet is impregnated with a polymeric mordant selected to stabilize indicators that generate detectable responses;
- and
- a separation layer disposed between the inner sheet and the outer sheet, wherein the separation layer is at least porous.
An indicating panel for an incontinence product, comprising:
- a porous inner sheet that is impregnated with a first indicator;
- wherein the first indicator is selected to respond to a target analyte by creating a detectable response;
- and
- a porous outer sheet adjacent to the inner sheet, wherein the outer sheet is impregnated with a polymeric mordant selected to stabilize indicators that generate detectable responses;
- wherein the polymeric mordant is poly[methyl acrylate-co-(3-acrylamidopropyl)trimethyl ammonium chloride].
An indicating panel for an incontinence product, comprising:
- a porous inner sheet that is impregnated with a first indicator;
- wherein the first indicator comprises poly(methyl vinyl ether-alt-maleic acid) (PMVEMA) and is configured to respond to a target analyte by creating a detectable response;
- and
- a porous outer sheet adjacent to the inner sheet, wherein the outer sheet is impregnated with a polymeric mordant selected to stabilize indicators that generate detectable responses.
