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.
Claims19
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.
3 more elements
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.
