Abstract

Print media which includes at least one ink-receiving layer comprising at least one anionic fluorosurfactant and may be positioned over the substrate and/or be supported by the substrate.

Claims

1. A print media, comprising:

a substrate;

at least one ink-receiving layer positioned over the substrate, the ink-receiving layer comprising surfactant, said surfactant being present in the at least one ink-receiving layer at from about 0.1 to about 1 part, and said surfactant being only anionic fluorosurfactant without any other surfactant present; and

at least one additional material layer positioned adjacent to the at least one ink-receiving layer.

2. The print media of claim 1, wherein the at least one ink-receiving layer further comprises at least one binder.

3. The print media of claim 1, further comprising at least one additional material layer positioned between the substrate and the at least one ink-receiving layer.

4. The print media of claim 3, wherein the at least one additional material layer comprises at least one binder.

5. The print media of claim 3, wherein the at least one additional material layer comprises at least one binder.

6. The print media of claim 1, wherein the at least one ink-receiving layer is directly affixed to the substrate.

7. The print media of claim 1, wherein the substrate further comprises a first side and a second side, and wherein at least one of the first side and the second side comprises a coating layer thereon comprised of polyethylene.

8. A print media, comprising:

a substrate;

at least one ink-receiving layer supported by the substrate, the ink-receiving layer comprising surfactant, said surfactant being present in the at least one ink-receiving layer at from about 0.1 to about 1 part, and said surfactant being only anionic fluorosurfactant without any other surfactant present; and

at least one additional material layer positioned adjacent to the at least one ink-receiving layer.

9. The print media of claim 8, wherein the at least one ink-receiving layer further comprises at least one binder.

10. The print media of claim 8, further comprising at least one additional material layer positioned between the substrate and the at least one ink-receiving layer.

11. The print media of claim 8, further comprising at least one additional material layer positioned over and above the at least one ink-receiving layer.

12. A method for producing a print media, comprising:

providing a substrate;

forming at least one ink-receiving layer in a position over the substrate, the ink-receiving layer comprising surfactant, said surfactant being present in the at least one ink-receiving layer at from about 0.1 to about 1 part, and said surfactant being only anionic fluorosurfactant without any other surfactant present; and

forming at least one additional material layer positioned adjacent to the at least one ink-receiving layer.

13. The method of claim 12, further comprising forming at least one additional material layer positioned between the substrate and the at least one ink-receiving layer.

14. The method of claim 12, further comprising forming at least one additional material layer in position over and above the at least one ink-receiving layer.
