Abstract
Methods for forming a translucent window on the inner surface of a liquid impermeable breathable film outer cover of an absorbent product, such as a diaper, for viewing a water dispersible ink to indicate when an insult has occurred are disclosed. Additionally, absorbent products having a translucent window and a water dispersible ink are disclosed.
Claims15
An absorbent product comprising:
- a liquid impermeable outer cover comprising a clearing varnish capable of forming a translucent window and a water dispersible ink applied over the translucent window, the clearing varnish having at least one of a number average molecular weight of from about 150 to about 1500, a melting point of from about 65° C. to about 95° C., and a melt index of from about 300 to about 1500;
- an absorbent material;
- and
- a liquid permeable inner layer, wherein the outer cover comprises from about 10 g/m2 to about 75 g/m2 clearing varnish.
An absorbent product comprising:
- a liquid impermeable outer cover comprising a clearing varnish capable of forming a translucent window and a water dispersible ink applied over the translucent window, the clearing varnish being selected from the group consisting of an epoxidized soybean oil, an ethylene-vinyl acetate copolymer, a tallow-based oleamide, a polyethylene glycol distearate, and combinations thereof, and the water dispersible ink comprising isopropyl alcohol, methyl alcohol, and an organic volatile;
- an absorbent material;
- and
- a liquid permeable inner layer, wherein the outer cover comprises from about 10 g/m2 to about 75 g/m2 clearing varnish.
A method of making an absorbent product comprising a translucent window for viewing a fading graphic, the method comprising:
- applying from about 10 g/m2 to about 75 g/m2 clearing varnish onto an inner surface of a liquid impermeable outer cover to form a translucent window, the clearing varnish having at least one of a number average molecular weight of from about 150 to about 1500, a melting point of from about 65° C. to about 95° C., and a melt index of from about 300 to about 1500;
- and
- printing a water dispersible ink over the translucent window.
