Abstract

A nonwoven substrate has a first surface and a second surface opposite the first surface. The first surface may include one or more printed portions, wherein at least one printed portion has a curable ink. Said printed portion may exhibit a Crosslinking Index of about 330 or less as determined by the Crosslinking Index Test Method herein and an IAR (Mineral Oil) of 1.30 or greater as determined by the IAR Test Method herein.

First claim

What is claimed is:

1. A nonwoven substrate comprising a first surface and a second surface opposite the first surface; wherein the first surface comprises one or more printed portions, wherein at least one printed portion comprises a curable ink; and wherein the at least one printed portion comprises a Crosslinking Index of about 330 or less as determined by the Crosslinking Index Test Method herein and an Ink Adhesion Rating (Mineral Oil) of about 1.30 or greater as determined by the Ink Adhesion Rating Test Method herein.

2. The nonwoven substrate of claim 1 wherein the curable ink comprises an e-beam curable ink.

3. The nonwoven substrate of claim 2 wherein the at least one printed portion further comprises a Crosslinking Index of about 100 or less and/or an Ink Adhesion Rating (Mineral Oil) of about 2.5 or greater.

4. The nonwoven substrate of claim 1 wherein the curable ink comprises an UV-curable ink.

5. The nonwoven substrate of claim 4 wherein the at least one printed portion further comprises a Crosslinking Index of about 200 or less.

6. The nonwoven substrate of claim 1 wherein the curable ink comprises any of the colors of cyan, magenta, yellow, black and combinations thereof.

7. The nonwoven substrate of claim 1 wherein the curable ink is at least partially disposed in a graphic and/or pattern.

8. An article comprising a topsheet, backsheet, and absorbent core disposed between the topsheet and backsheet and a component comprising the nonwoven substrate of claim 1 .

9. The nonwoven substrate of claim 1 wherein the at least one printed portion comprises an Ink Penetration Depth of about 250 microns or less.

10. The nonwoven substrate of claim 1 further comprising a basis weight of about 8 gsm to about 65 gsm.

11. The nonwoven substrate of claim 1 further comprising polyolefin fibers.

12. A nonwoven substrate comprising a first surface and a second surface opposite the first surface; wherein the first surface comprises a printed portion comprising a curable ink; wherein the printed portion comprises a Crosslinking Index of about 330 or less as determined by the Crosslinking Index Test Method herein and a ΔE* of about 7 or greater as determined by the ΔE* Determination Test Method herein.

13. The nonwoven substrate of claim 12 wherein the curable ink comprises an UV curable ink and the printed portion comprises a ΔE* of from about 12 to about 50.

14. The nonwoven substrate of claim 12 wherein the curable ink comprises a Crosslinking Index of about 200 or less as determined by the Crosslinking Index Test Method herein.

15. The nonwoven substrate of claim 12 wherein the curable ink comprises an e-beam curable ink.

16. An article comprising a topsheet, backsheet and absorbent core disposed between the topsheet and backsheet and a component comprising the nonwoven substrate of claim 12 .

17. A nonwoven substrate comprising a first surface and a second surface opposite the first surface; wherein the first surface comprises a printed portion comprising a curable ink; wherein the curable ink comprises a Crosslinking Index of about 330 or less, an Ink Adhesion Rating (Dry) of about 1.5 or greater, a ΔE* of about 10 or greater, an Ink Penetration Depth of about 250 microns or less.

18. The nonwoven substrate of claim 17 wherein the curable ink comprises an e-beam ink.

19. The nonwoven substrate of claim 17 wherein the curable ink comprises a UV ink.

20. An article comprising a topsheet, backsheet and absorbent core disposed between the topsheet and backsheet and a component comprising the nonwoven substrate of claim 17 .
