What is claimed is: 1. A disposable absorbent article comprising: a) a liquid pervious topsheet; b) a liquid impervious backsheet that is at least partially joined to the topsheet; c) an absorbent core disposed at least partially between the topsheet and the backsheet; and d) a wetness indicator di
What is claimed is: 1. A disposable absorbent article comprising: a) a liquid pervious topsheet; b) a liquid impervious backsheet that is at least partially joined to the topsheet; c) an absorbent core disposed at least partially between the topsheet and the backsheet; and d) a wetness indicator disposed between the absorbent core and the backsheet and in liquid communication with the absorbent core; the wetness indicator comprising a hidden central graphic and a background graphic; wherein the hidden central graphic comprises a permanent color composition and the background graphic comprises at least one responsive color composition and that, upon wetting, the background graphic exhibits a visible change resulting in the hidden central graphic being revealed, wherein the visible change is selected from the group consisting of a color change, a graphic change, and combinations thereof. 2. The article of claim 1 wherein the responsive color composition comprises: a) from about 1% to about 10%, by weight of the composition, of solid pigment particles; b) from about 1% to about 10%, by weight of the composition, of a fluid dyestuff; and c) from about 10% to about 98%, by weight of the composition, of a solvent. 3. The article of claim 1 wherein the responsive color composition comprises: a) from about 1% to about 10%, by weight of the composition, of a fluid dyestuff; and b) from about 50% to about 99%, by weight of the composition, of a solvent; and wherein said responsive color composition is disposed adjacent to a varnish coating. 4. The article of claim 2 wherein the solvent is selected from a non-aqueous solvent, an aqueous solvent, and combinations thereof. 5. The article of claim 3 wherein the solvent is a non-aqueous solvent. 6. The article of claim 1 wherein the central graphic comprises a second responsive color composition and wherein, upon wetting, the central graphic exhibits a visible change selected from the group consisting of a color change, a graphic change, and combinations thereof. 7. The article of claim 6 wherein the second responsive color composition comprises: a) from about 5% to about 10%, by weight of the composition, of solid pigment particles; b) from about 5% to about 10%, by weight of the composition, of a fluid dyestuff; and c) from about 10% to about 80%, by weight of the composition, of a solvent. 8. The article of claim 3 wherein the central graphic comprises a second responsive color composition and wherein, upon wetting, the central graphic exhibits a visible change selected from the group consisting of a color change, a graphic change, and combinations thereof. 9. The article of claim 8 wherein the second responsive color composition comprises: a) from about 1% to about 10%, by weight of the composition, of solid pigment particles; b) from about 1% to about 10%, by weight of the composition, of a fluid dyestuff; and c) from about 50% to about 98%, by weight of the composition, of a solvent. 10. The article of claim 8 wherein the second responsive color composition comprises: a) from about 1% to about 10%, by weight of the composition, of a fluid dyestuff; and b) from about 50% to about 99%, by weight of the composition, of a solvent; and wherein said second responsive color composition is disposed adjacent to the varnish coating. 11. A method of printing a wetness indicator onto an absorbent article: a) providing an absorbent article wherein said article comprises a topsheet, a backsheet and an absorbent core; b) disposing between said backsheet and said absorbent core via printing a wetness indicator that is in liquid communication with the absorbent core wherein the wetness indicator comprises a hidden central graphic and a background graphic; wherein the hidden central graphic comprises a permanent color composition and the background graphic comprises at least one responsive color composition and that, upon wetting, the background graphic exhibits a visible change resulting in the hidden central graphic being revealed, wherein the visible change is selected from the group consisting of a color change, a graphic change, and combinations thereof.
