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.
Claims18
An ink-printed substrate, comprising:
- a. a substrate;
- b. a water-based ink composition printed on the substrate, forming a water-based ink printed area, wherein the water-based ink composition comprises from about 5% to about 30% of a very low Tg° C. water-based polymer component and from about 20% to about 45% of a binder;
- c. an overprint varnish comprising a very low Tg° C. water-based polymer component and a binder;
- wherein said ink-printed substrate has an average crockfastness of at least about 2.5 or greater;
- wherein the substrate is non-woven fibrous web formed by a spunbonding process.

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 non-woven fibrous web formed by a spunbonding process, the non-woven fibrous web having at least one water-based ink and at least one water-based overprint varnish printed thereon, wherein the water-based ink composition comprises from about 5% to about 30% of a very low Tg° C. water-based polymer component and from about 20% to about 45% of a binder, wherein overprint varnish comprising a very low Tg° C. water-based polymer component and a binder;
- wherein an area of the non-woven fibrous web 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.
An ink-printed substrate, comprising:
- a. a substrate selected from the group consisting of films, fibrous polyolefin webs, polyolefin web, cellulosic webs, elastomeric webs, laminates, or combinations thereof;
- b. a water-based ink composition printed on the substrate, forming a water-based ink printed area, wherein the water-based ink composition comprises from about 5% to about 30% of a very low Tg° C. water-based polymer component and from about 20% to about 45% of a binder;
- c. an overprint varnish comprising a very low Tg° C. water-based polymer component and a binder;
- wherein said ink-printed substrate has an average crockfastness of at least about 2.5 or greater.
