Colorant solvent system, methods of use, and articles
Aspects of the present disclosure relate to color compositions and methods of making a printed layer using the color composition as well as an article that can include the printed layer.
1. An article comprising:
an article having a first side, the first side comprising a polymeric material including a printed layer comprising a color composition,
wherein the color composition comprises:
about 5-30 weight percent of 2-pyrrolidone,
about 25-55 weight percent of sulfolane,
about 15-55 weight percent of ε-caprolactone, and
about 1-25 weight percent of a colorant.
2. The article of claim 1 , wherein the color composition comprises:
about 5-10 weight percent of 2-pyrrolidone,
about 25-45 weight percent of sulfolane,
about 25-45 weight percent of ε-caprolactone, and
about 1-15 weight percent of the colorant.
3. The article of claim 1 , wherein the polymeric material comprises one or more of polyurethane, polyether, polyester, polyurea, polyamide, polyolefin, or any combination thereof.
4. The article of claim 1 , wherein the polymeric material comprises one or more polyurethanes, or one or more polyester-polyurethane copolymers.
5. The article of claim 4 , wherein the polymeric material comprises one or more thermoplastic polyurethane.
6. The article of claim 4 , wherein the polymeric material comprises one or more thermoplastic polyester-polyurethane copolymer.
7. The article of claim 1 , wherein the first side of the article has a gas transmission rate of 15 cm 3 /m 2 ·atm·day or less for nitrogen for an average wall thickness of 0.5 mm (20 mils).
8. The article of claim 1 , wherein the first side of the article comprises a film, and the film includes an exposed layer comprising the polymeric material.
9. The article of claim 8 , wherein the film is a multi-layer film including two or more layers of the polymeric material alternating with one or more layers of a barrier material comprising one or more polymers having a lower gas permeability than the polymeric material.
10. The article of claim 8 , wherein the printed layer penetrates into an outer portion of the exposed layer of the film.
11. The article of claim 10 , wherein the printed layer penetrates into the outer portion of the exposed layer of the film, but not into a layer of a barrier material adjacent to the exposed layer of the film.
12. The article of claim 11 , wherein the barrier material comprises one or more ethylene-vinyl alcohol copolymers.
13. The article of claim 1 , wherein the printed layer is a dried product of the color composition and a first composition, wherein the first composition comprises a dispersion of polymers.
14. The article of claim 13 , wherein the printed layer includes a matrix of crosslinked polymers.
15. The article of claim 12 , wherein a matrix of crosslinked polymers includes crosslinked polyurethane homopolymers or copolymers or both.
16. The article of claim 15 , wherein the matrix of crosslinked polymers includes crosslinked polyester polyurethanes.
17. The article of claim 11 , wherein the printed layer includes a product of crosslinking a first composition, and wherein the first composition optionally comprises uncrosslinked polyurethane polymers.
18. The article of claim 17 , wherein the uncrosslinked polyurethane polymers are thermoplastic polyurethane polymers.
19. The article of claim 1 , wherein the printed layer extends from a surface of the first side of the article into the polymeric material.
20. An article comprising:
an article having a first side, the first side comprising a polymeric material including a printed layer comprising a color composition,
wherein the color composition comprises:
about 5-30 weight percent of 2-pyrrolidone,
about 25-55 weight percent of sulfolane,
about 15-55 weight percent of ε-caprolactone, and
about 1-25 weight percent of a colorant,
wherein the first side of the article comprises a film, and the film includes an exposed layer comprising the polymeric material, and
wherein the printed layer is integrated into an outer portion of the exposed layer of the film.
