Abstract
Disclosed herein are methods of electrostatically printing a cyclodextrin composition on a substrate, the method including forming an electrostatically printable composition comprising a polymer and one or more cyclodextrins, one or more cyclodextrin inclusion complexes, or a combination thereof, and electrostatically printing the composition on a substrate. Also described are electrostatically printable compositions, methods of making the compositions, printing systems employing the compositions, substrates having the composition electrostatically printed thereon, laminates thereof, and uses of the printed substrates and laminates.
Claims32
A printed substrate comprising a substrate having a first major surface, the printed substrate comprising a first electrostatically printable composition electrostatically printed and at least partially fused on at least a portion of the area of the first major surface, the first electrostatically printable composition comprising a particulate comprising a cyclodextrin complexed with a first medicament, further wherein the cyclodextrin is present in the printable composition at about 2 wt % to 30 wt %.
A printed substrate comprising:
- a substrate having a first major surface and a second major surface;
- and
- a first electrostatically printable composition electrostatically printed on at least a portion of the first major surface and at least partially fused thereon, the first electrostatically printable composition comprising a particulate comprising cyclodextrin complexed with a first compound selected from an antimicrobial, a fungicide, an insecticide, a pesticide, a preservative, or a fragrance, further wherein the cyclodextrin is present in the printable composition at about 2 wt % to 30 wt %;
- and
- an adhesive disposed on at least a portion of the second major surface of the substrate.
A kit comprising a plurality of die-cut stickers, the stickers comprising the printed substrate of claim 1, claim 14, or claim 20.
A printed substrate comprising a substrate having a first major surface, the printed substrate comprising a first electrostatically printable composition electrostatically printed and at least partially fused on at least a portion of the area of the first major surface, the first electrostatically printable composition comprising a cyclodextrin complexed with a first compound that is a medicament, a fragrance, a colorant, a fungicide, an insecticide, a pesticide, an antimicrobial, a preservative, or 1-methylcyclopropene, further wherein the cyclodextrin is present in the printable composition at about 2 wt % to 30 wt %.
