Printer-compatible, pre-embossed films
View Patent ↗Decorative films, useful for making a wide range of decorative laminates, that have a relatively deep texture on one major face and a relatively smoother, print receptive surface on the other major face. Notwithstanding the deep texture, the films have superb tracking characteristics and are compatible with a wide variety of automated printing operations. This allows automated printing equipment to print information directly onto the films.
1. A decorative film, comprising:
a) a first, textured major face comprising plurality of protuberances having a plurality of different shapes and a plurality of different dimensions, wherein said plurality of different shapes comprise at least circular shaped protuberances, and wherein said plurality of protuberances are randomly arranged on the first major face, said first major surface having an Ra surface roughness greater than about 100 microinches;
b) a second, print receptive major face, the second major face being relatively smoother than the first major face, and the second major face having an Ra surface roughness less than 100 microinches, wherein the ratio of the Ra surface roughness of the first major face of the film to the Ra surface roughness of the second major face of the film is in the range from about 1.1:1 to about 500:1; and
c) decorative information printed onto the second major face;
wherein the film is a single-layer film that comprises polyvinyl chloride.
2. The film of claim 1 , wherein the film comprises less than 2 parts by weight of total plasticizer per 100 parts by weight of the film.
3. The film of claim 1 , wherein the film comprises less than 0.1 parts by weight of total plasticizer per 100 parts by weight of the film.
4. The film of claim 1 , wherein the plurality of protuberances are directional.
5. The film of claim 1 , wherein the plurality of protuberances comprise acicular, meandering protuberances.
6. The film of claim 5 , wherein the protuberances comprise branches.
7. The film of claim 1 , wherein the first major face has an Ra surface roughness greater than about 120 microinches.
8. The film of claim 1 , wherein the first major face has an Ra surface roughness greater than about 150 microinches.
9. The film of claim 1 , wherein the first major face has an Ra surface roughness of 160 to 190 microinches.
10. The film of claim 1 , wherein the first major face has an Ra surface roughness of 120 to 300 microinches.
11. The film of claim 1 , wherein the second major face has an Ra surface roughness in the range from 60 microinches to 90 microinches.
12. The film of claim 1 , wherein the second major face has an Ra surface roughness of less than about 60 microinches.
13. The film of claim 1 , wherein the ratio of the Ra surface roughness of the first major face to the second major face is in the range from about 3:2 to about 10:1.
14. The film of claim 1 , wherein the ratio of the Ra surface roughness of the first major face to the second major face is in the range from about 3:2 to about 3:1.
15. The decorative film of claim 1 , wherein the film is a pre-embossed film.
16. A decorative laminate, comprising;
a) a substrate; and
b) a decorative film bonded directly or indirectly to the substrate, said decorative film comprising:
1) a first, textured major face comprising plurality of protuberances having a plurality of different shapes and a plurality of different dimensions, wherein said plurality of different shapes comprise at least circular shaped protuberances, and wherein said plurality of protuberances are randomly arranged on the first major face, said first major surface having an Ra surface roughness greater than about 100 microinches;
2) a second, print receptive major face, the second major face being relatively smoother than the first major face, and the second major face having an Ra surface roughness less than 100 microinches, wherein the ratio of the Ra surface roughness of the first major face of the film to the Ra surface roughness of the second major face of the film is in the range from about 1.1:1 to about 500:1; and
3) decorative information printed onto the second major face; wherein the film is a single-layer film that comprises polyvinyl chloride.
17. The decorative laminate of claim 16 , wherein the plurality of protuberances are directional.
18. The decorative laminate of claim 16 , wherein the plurality of protuberances comprise acicular, meandering protuberances.
19. The decorative laminate of claim 16 , wherein the first major face has an Ra surface roughness greater than about 120 microinches.
20. The decorative laminate of claim 16 , wherein the ratio of the Ra surface roughness of the first major face to the second major face is in the range from about 3:2 to about 10:1.
