Abstract

The absorbent article provides a signal viewable from the top surface of the absorbent article which gives a perception of depth within the absorbent article. This creation of depth perception is accomplished by the use of at least two tones within a color and/or by the use of multiple tones and multiple colors operating together to create a perception of depth within the absorbent article. At least one tone contains a graphic.

Claims

1. An absorbent article having an upper surface, a lower surface and a periphery, comprising:

a topsheet having a bottom surface and a viewing surface positioned opposite to the bottom surface, the viewing surface facing upwardly towards the upper surface of the absorbent article;

a backsheet having a garment facing surface and a user facing positioned oppositely to the garment facing surface, the backsheet being joined to the topsheet;

an absorbent core having a top surface and a bottom surface positioned opposite to the top surface, the absorbent core being positioned between the topsheet and the backsheet; and

the absorbent core having a colored portion printed thereon, the colored portion being viewable from the viewing surface of the topsheet, the colored portion having a first shade and a second shade, wherein the first shade comprises a first graphic, the first shade being positioned substantially within the second shade, the second shade being different from the first shade, the shades operating to create a perception of depth within the absorbent article by a user looking upon the viewing surface of the topsheet.

2. The absorbent article of claim 1 wherein said second shade comprises a second graphic.

3. The absorbent article of claim 1 wherein said first shade comprises a first graphic and said second shade comprises a second graphic.

4. The absorbent article of claim 3 wherein said first graphic comprises a different shape than said second graphic.

5. The absorbent article of claim 3 wherein said first graphic has a first color and a second graphic has a second color.

6. The absorbent article of claim 3 wherein the color of the first graphic, the second graphic, the color of the first shade, the color of the second shade of the colored portion, and the non-colored portion are measured by the Hunter Reflectance Meter test according to the colors'"'"' L, a, and b values, the L, a, and b values being measured from the viewing surface of the topsheet inboard of the absorbent article'"'"'s periphery.

7. The absorbent article of claim 6 wherein the color differences between the first graphic, the second graphic, and the non-colored portion are measured at a first point, a second point, and a third point on the viewing surface of the topsheet inboard of the periphery of the absorbent article, the first point being measured within the first graphic, the second point being measured within the second graphic, and the third point being measured within the non-colored portion of the absorbent article, the color differences being calculated using the L, a, and b values by the formula

Δ

E=[(L*_x·

−

L*_y)²+(a*_x·

−

a*_y)²+(b*_x−

b*_y)²]^1/2

8. The absorbent article of claim 7 wherein the difference in color between the first graphic and the second graphic is at least 3.5.

9. The absorbent article of claim 7 wherein the difference in color between the first graphic and the non-colored portion is at least 6.

10. The absorbent article of claim 7 wherein the difference in color between the second shade and the non-colored portion is at least 3.5.

11. The absorbent article of claim 1 wherein the size of the colored portion ranges from about 5% to about 98% of the viewing surface of the topsheet.

12. An absorbent article having an upper surface, a lower surface and a periphery, comprising:

a topsheet having a bottom surface and a viewing surface positioned opposite to the bottom surface, the viewing surface facing upwardly towards the upper surface of the absorbent article;

a backsheet having a garment facing surface and a user facing positioned oppositely to the garment facing surface, the backsheet being joined to the topsheet;

an absorbent core having a top surface and a bottom surface positioned opposite to the top surface, the absorbent core being positioned between the topsheet and the backsheet; and

the absorbent core having a colored portion printed thereon, the colored portion being viewable from the viewing surface of the topsheet, the colored portion having a first shade and a second shade, the first shade being positioned substantially within the second shade, wherein the first shade of the color is darker than the second shade of the color, and wherein the first shade comprises a first graphic, the shades operating to create a perception of depth within the absorbent article by a user looking upon the viewing surface of the topsheet.

13. The absorbent article of claim 12 wherein the first graphic comprises a color.

14. The absorbent article of claim 13 wherein said first graphic is a flower.

15. An absorbent article having an upper surface, a lower surface and a periphery, comprising:

a topsheet having a bottom surface and a viewing surface positioned opposite to the bottom surface, the viewing surface facing upwardly towards the upper surface of the absorbent article;

a backsheet having a garment facing surface and a user facing positioned oppositely to the garment facing surface, the backsheet being joined to the topsheet;

an absorbent core having a top surface and a bottom surface positioned opposite to the top surface, the absorbent core being positioned between the topsheet and the backsheet; and

the absorbent core having a colored portion all printed thereon, the colored portion being viewable from the viewing surface of the topsheet, the colored portion having a first shade and a second shade, the first shade being positioned substantially within the second shade, the second shade being darker than the first shade, said first shade comprises a first graphic, the shades operating to create a perception of depth within the absorbent article by a user looking upon the viewing surface of the topsheet.
