Problems solved by technology
Without being bound by theory, it is believed that color-changing compositions where the color change is due to the color-changing composition being wetted with an aqueous liquid are no longer able to maintain their original color state when standard relative humidity conditions are exceeded.
For example, a color-changing composition printed on a polymeric substrate of a diaper may experience premature exposure to conditions other than standard room temperature and standard relative humidity during the manufacturing process, warehouse storage, product distribution and end user storage up until the time of use.
Premature exposure of the color-changing composition to levels of relative humidity higher than standard relative humidity can affect the indicator efficacy such that the end user will not receive visual communication of the change when the color-changing composition is wetted with an aqueous liquid.
In addition to the needs identified above, there are unmet needs associated with using color-changing materials as components of personal care absorbent articles, such as disposable diapers.

Abstract
The present disclosure relates to a color-changing composition and to a substrate having the color-changing compositions disposed thereon. The color-changing composition includes a leuco dye, a color-developer and a desensitizer. The color-changing composition changes from a colorless or largely colorless composition to color upon being wetted with an aqueous liquid. The color-changing composition remains colorless or largely colorless prior to exposure to high relative humidity conditions.
Description
[0001]The present disclosure relates to a color-changing composition that is color-appearing in the presence of an aqueous liquid. In particular, the present disclosure pertains to a medium or an ink that remains colorless or largely colorless in high relative humidity and when wetted with an aqueous liquid, changes to higher intensity color.BACKGROUND OF THE DISCLOSURE[0002]Many products, including consumer and professional products, are more effectively used by an end user when the product includes a feature that can communicate or signal to the user a particular condition or a relative level or degree of use. An example of a visual, communicative feature is a wetness indicator made by applying a color-changing composition to a substrate. Wetness indicators can either indicate a change in condition or a degree of use through a change from colorless or largely colorless to colored or through a change in color intensity.[0003]Exemplary conditions that could be monitored using a wetn...
