Patent ID: 7732046

Claim:
A fluid contact indicator adhesive article comprising a first layer comprising a fluid transport substrate, the fluid transport substrate further comprises a layer consisting of a low molecular weight hydrophilic polymer resin and a filler to control opacity of the substrate, the first layer having a first major surface and a second major surface; a second layer comprising a dry fluid transportable ink, wherein the fluid transportable ink is capable of migrating through the fluid transport substrate when exposed to fluid, the second layer being associated with the second major surface of the first layer; and an adhesive layer associated with the second layer opposite the first layer, wherein the hydrophilic polymer resin layer is provided between the second layer and the fluid transport substrate, and wherein the filler is present in an amount greater than 5 weight percent of the total weight of the polymer resin and filler combined, wherein upon exposure to a fluid, the adhesive article undergoes a substantial color change on at least a portion of the fluid substrate.
