Water-Based Wetness-Indicating Composition and Sensor |
摘要 |
A color-appearing ink composition includes a surfactant blend of at least two non-ionic surfactants having hydrophilic-lipophilic balance values greater than 10, or a non-ionic surfactant having a hydrophilic-lipophilic balance value greater than 10 and a charged surfactant. The composition includes one or more water-insoluble leuco dyes, a developer and a desensitizer. The composition may be applied to a substrate to form a sensor. |

1. A method for preparing a substrate, the method comprising the steps of:
preparing a surfactant blend comprising at least two surfactants having different hydrophilic lipophilic balance profiles; preparing a solubilized active by solubilizing a water-insoluble leuco dye with the surfactant blend and a developer; combining the solubilized active with a binder, a stabilizer and water to create a colored solution; and applying the colored solution to the substrate; and drying the substrate so that the applied colored solution becomes colorless. |
