Abstract

An ink-printed substrate comprising a substrate and water-based ink composition printed on the substrate, wherein the ink-printed substrate has an average crockfastness of at least about 2.5 or greater.

First claim

What is claimed is:

1. An ink-printed substrate, comprising:
a. a substrate selected from the group consisting of a non-woven, a film, a fibrous polyolefin web, a polyolefin web, a cellulosic web, an elastomeric web, laminates of one or more of the above, and combinations of one or more of the above;
b. a water-based ink composition printed on the substrate, forming a water-based ink printed area; and
c. an overprint varnish comprising a very low Tg° C. water-based polymer component and one of the group consisting of a binder, a resolubility agent, a de-tackifier, water and combinations thereof;
wherein the ink-printed substrate has an average crockfastness of at least about 2.5 or greater;
wherein the ink composition has a color density of at least about 0.48 or greater.

2. The ink-printed substrate of claim 1 , wherein the substrate is a non-woven.

3. The ink-printed substrate of claim 1 , wherein the substrate is a film.

4. The ink-printed substrate of claim 1 , wherein the substrate is a fibrous polyolefin web.

5. The ink-printed substrate of claim 1 , wherein the substrate is a polyolefin web.

6. The ink-printed substrate of claim 1 , wherein the substrate is a cellulosic web.

7. The ink-printed substrate of claim 1 , wherein the substrate is an elastomeric web.

8. The ink-printed substrate of claim 1 , wherein the substrate is a laminate of one or more of a non-woven, film, fibrous polyolefin web, polyolefin web, cellulosic web, and elastomeric web.

9. The ink-printed substrate of claim 1 , wherein the substrate is a combination of one or more of a non-woven, film, fibrous polyolefin web, polyolefin web, cellulosic web, and elastomeric web.

10. The ink-printed substrate of claim 1 , wherein the substrate exhibits a low surface tension.

11. The ink-printed substrate of claim 1 , wherein the substrate is at least one of hydrophobic, apolar, or inert.

12. The ink-printed substrate of claim 1 , wherein the water-based ink composition comprises a very low Tg° C. water-based polymer component.

13. The ink-printed substrate of claim 12 , wherein a Tg° C. of the water-based polymer is less than about −80° C.

14. The ink-printed substrate of claim 1 , wherein the water-based ink composition further comprises a binder.

15. The ink-printed substrate of claim 1 , wherein the overprint varnish is applied to the water-based ink printed area.

16. The ink-printed substrate of claim 1 , wherein the average crockfastness of an area of the substrate comprising both the water-based overprint varnish and the water-based ink composition is at least about 4.0 or greater.

17. The ink printed substrate of claim 1 , wherein the substrate is pretreated with a surface treatment selected from the group consisting of plasma treatment, UV treatment, flame treatment, heat treatment, abrasion treatment, and corona treatment.

18. The ink-printed substrate of claim 1 , wherein a leachability colorfastness rating is less than about 5.

19. A disposable absorbent article, comprising: a topsheet, a backsheet, and an absorbent core between the topsheet and the backsheet, the backsheet comprising an ink-printed substrate selected from the group consisting of a non-woven, a film, a fibrous polyolefin web, a polyolefin web, a cellulosic web, an elastomeric web, laminates of one or more of the above, and combinations of one or more of the above, the ink-printed substrate having at least one water-based ink and at least one water-based overprint varnish printed thereon, wherein the at least-one water-based overprint varnish comprises a very low Tg° C. water-based polymer component and one of the group consisting of a binder, a resolubility agent, a de-tackifier, water and combinations thereof; wherein an area of the ink-printed substrate comprising both the water-based overprint varnish and the water-based ink composition has an average crockfastness of at least about 3.5 or greater, and wherein the ink-printed substrate is pretreated with a corona treatment of from about 1.0 to about 4.0 watts per square feet per minute; wherein the ink composition has a color density of at least about 0.48 or greater.
