Abstract

The present disclosure is directed to articles that include a cured coating that includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating can include a matrix of crosslinked polymers. The cured coating is a product of crosslinking a coating composition comprising uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier to form the matrix of crosslinked polymers), wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers. The matrix of crosslinked polymers can be elastomeric. The present disclosure is also directed to articles including these bladders, methods of forming these bladders, and methods of making articles including these bladders, where the bladders include the cured coating.

First claim

What is claimed is:

1. A coated article comprising:
a cushioning element having an externally-facing side comprising a first elastomeric material; and
a cured coating disposed on the first elastomeric material of the externally-facing side, wherein the cured coating includes a plurality of pigment particles or dye entrapped in a matrix of crosslinked polyurethanes, wherein the cured coating is an elastomeric cured coating and has a percent elongation of at least 100 percent.

2. The article of claim 1 , wherein the cured coating is a product of crosslinking a coating composition comprising a dispersion of uncrosslinked polyester polyurethanes in a carrier to form the matrix of crosslinked polymers.

3. The coated article of claim 1 , wherein the matrix of crosslinked polyurethanes includes crosslinked polyester polyurethane elastomer.

4. The coated article of claim 1 , wherein the cushioning element is an inflated bladder having a bladder wall with an interior-facing side defining an interior region of the bladder and an exterior-facing side opposing the interior-facing side; wherein the first elastomeric material defines the interior-facing side or the exterior-facing side or both; and wherein the cured coating is disposed on the exterior-facing side or on the interior-facing side or on both.

5. The coated article of claim 4 , wherein the bladder wall includes a thermoplastic polyurethane film on the exterior-facing side of the bladder wall or the interior-facing side of the bladder wall, wherein the elastomeric cured coating is disposed on the thermoplastic polyurethane film.

6. The coated article of claim 1 , wherein the cured coating reduces a level of ultraviolet light reaching the first elastomeric material as compared to a substantially identical article without the cured coating.

7. The coated article of claim 1 , wherein the article is a sole structure for an article of footwear, and the cushioning element is a midsole component of the sole structure.

8. The coated article of claim 1 , wherein the first elastomeric material includes a polyurethane homopolymer or copolymer, a polyamide homopolymer or copolymer, a polyether homopolymer or copolymer, a polyester homopolymer or copolymer, or any combination thereof.

9. The coated article of claim 8 , wherein a polymeric component of the first elastomeric material consisting of all polymers present in the first elastomeric material consists essentially of one or more polyurethane homopolymers, one or more polyurethane copolymers, or any combination thereof.

10. A coated article comprising:
a cushioning element having an externally-facing side comprising a first foamed polymeric material; and
a cured coating disposed on the first polymeric material of the externally-facing side, wherein the cured coating includes a plurality of pigment particles or a dye entrapped in a matrix of crosslinked polyurethanes, wherein the cured coating is an elastomeric cured coating and has a percent elongation of at least 100 percent.

11. The coated article of claim 10 , wherein the first foamed polymeric material comprises a vinyl acetate homopolymer or copolymer, an acrylate homopolymer or copolymer, a styrene homopolymer or copolymer, an olefinic homopolymer or copolymer, or any combination thereof.

12. The coated article of claim 10 , wherein the cured coating reduces a level of ultraviolet light reaching the first foamed polymeric material as compared to a substantially identical article without the cured coating.

13. The coated article of claim 10 , wherein the first foamed polymeric material includes a polyurethane homopolymer or copolymer, a polyamide homopolymer or copolymer, a polyether homopolymer or copolymer, a polyester homopolymer or copolymer, or any combination thereof.

14. The coated article of claim 10 , wherein the matrix of crosslinked polyurethanes includes crosslinked polyester polyurethane elastomer.

15. The coated article of claim 10 , wherein the article is a sole structure for an article of footwear, and the cushioning element is a midsole component of the sole structure.

16. A coated article comprising:
a cushioning element having an externally-facing side comprising a first elastomeric material; and
a cured coating disposed on the first elastomeric material of the externally-facing side, wherein the cured coating includes a plurality of pigment particles or a dye entrapped in a matrix of crosslinked polyurethanes, wherein the cured coating is an elastomeric cured coating and has a percent elongation of at least 100 percent;
wherein the cured coating reduces a level of water reaching the first polymeric material as compared to a substantially identical article without the cured coating.

17. The coated article of claim 16 , wherein the cured coating reduces a level of ultraviolet light reaching the first elastomeric material as compared to a substantially identical article without the cured coating.

18. The coated article of claim 16 , wherein the first elastomeric material includes a polyurethane homopolymer or copolymer, a polyamide homopolymer or copolymer, a polyether homopolymer or copolymer, a polyester homopolymer or copolymer, or any combination thereof.

19. The coated article of claim 16 , wherein the matrix of crosslinked polyurethanes includes crosslinked polyester polyurethane elastomer.

20. The coated article of claim 16 , wherein the article is a sole structure for an article of footwear, and the cushioning element is a midsole component of the sole structure.
