Absorbent article having a multilayer visual signal
An absorbent article and method of making an absorbent article. The absorbent article has a first layer and a second layer in facing relationship with one another. The first layer has a first imparted colored region coincident with the longitudinal centerline. The second layer has a second imparted colored region laterally more extensive in a direction orthogonally away from the longitudinal centerline than the first imparted colored region. The second imparted colored region extends across the longitudinal centerline and has free ends. The absorbent article has a background region. The first imparted colored region and the second imparted colored region differ in color as compared to the background region.
1. An absorbent article having a body facing surface, a garment facing surface opposing said body facing surface, a centroid, a longitudinal centerline, and a transverse centerline orthogonal to said longitudinal centerline and intersecting said longitudinal centerline at said centroid, said absorbent article comprising:
a background region;
a first layer comprising a first imparted colored region, said first imparted colored region coincident with said longitudinal centerline, said first imparted colored region comprising only a portion of the first layer; and
a second layer in facing relationship with said first layer, said second layer comprising a second imparted colored region, said second imparted colored region being laterally more extensive in a direction orthogonally away from said longitudinal centerline than said first imparted colored region, said second imparted colored region having free ends, said second imparted colored region extending across said longitudinal centerline and continuous between said free ends, said second imparted colored region comprising only a portion of the second layer;
wherein said first imparted colored region and said second imparted colored region differ in color from said background region;
wherein said background region, said first imparted colored region, and said second imparted colored region are viewable from said body facing surface.
2. The absorbent article according to claim 1 , wherein said first imparted colored region is coincident with said centroid.
3. The absorbent article according to claim 1 , wherein said absorbent article comprises two second imparted colored regions, wherein said first imparted colored region is between said two second imparted colored regions.
4. The absorbent article according to claim 1 , wherein said first imparted colored region and said second imparted colored region are spaced apart from one another along said longitudinal centerline.
5. The absorbent article according to claim 1 , wherein said first imparted colored region and said second imparted colored region at least partially overlap one another along said longitudinal centerline.
6. The absorbent article according to claim 1 , wherein said absorbent article has a periphery, wherein said background region is between said second imparted colored region and said periphery.
7. The absorbent article according to claim 1 , wherein said first imparted colored region is a substantially elongated shape.
8. The absorbent article according to claim 1 , wherein said first imparted colored region and said second imparted colored region are substantially surrounded by said background region.
9. The absorbent article according to claim 1 , wherein said first imparted colored region and said second imparted colored region are within a CIELab color space volume of less than about 200.
10. The absorbent article according to claim 1 , wherein said first imparted colored region and said second imparted colored region are within a CIELab color space volume of less than about 50.
11. The absorbent article according to claim 1 , wherein said absorbent article has a periphery, wherein said first imparted colored region has a width less than about 50% of the maximum distance between portions of said periphery coincident with said transverse centerline.
12. The absorbent article according to claim 1 , wherein said first imparted colored region, said second imparted colored region, and said background region are measured by a Hunter Reflectance Meter test according to the colors L*, a*, and b*, the L*, a*, and b* values being measured from said body facing surface, wherein said first imparted colored region and said second imparted colored region have a color difference, the color difference being calculated using the L*, a*, and b* values by the formula ΔE=[(L* X .−L* Y ) 2 +(a* X .−a* Y ) 2 +(b* X −b* Y ) 2 ] 1/2 , wherein said ΔE between said first imparted colored region and said background region is at least about 1 and wherein said ΔE between said second imparted colored region and said background region is at least about 1.
13. The absorbent article according to claim 1 , wherein said second imparted colored region is substantially arcuate shaped.
14. The absorbent article according to claim 1 , wherein said second imparted colored region is substantially arcuate shaped, and symmetric about said longitudinal centerline, and has two free ends, wherein said two free ends of said second imparted colored region are located closer to said transverse centerline than other portions of said second imparted colored region.
15. The absorbent article according to claim 1 , wherein said first layer is a nonwoven and fibers from said nonwoven protrude through said second layer.
16. The absorbent article according to claim 1 , wherein said second imparted colored region is continuous between said free ends.
