Abstract

Printing layers and films for printing are disclosed. Methods for preparing such films also are disclosed.

Claims (46)

1. A film for printing comprising:

a print layer comprising a plurality of layers;

a core layer;

an adhesive layer;

wherein the core layer is between the print layer and the adhesive layer, and wherein at least one of the layers of the plurality of layers of the print layer comprises a blend of at least one high absorption capacity material and at least one low absorption capacity material;

wherein the core layer comprises at least one polyolefin;

wherein the high absorption capacity material is selected from the group consisting of poly(methyl methacrylate), modified poly(methyl methacrylate), impact modified polystyrene, styrene acrylic copolymer, styrene-olefin copolymer, styrene-acrylic-olefin copolymer, acrylonitrile butadinene styrene polymer, styrene acrylonitrile polymer, and copolyester polymer and the low absorption capacity material comprises an olefin polymer; and

wherein an absorption gradient is present between at least two adjacent layers of the plurality of layers comprising the print layer.

2. The film of claim 1 wherein the polyolefin of the core layer is polyethylene.

3. The film of claim 2 wherein the polyethylene is selected from the group consisting of low density polyethylene, medium density polyethylene, and high density polyethylene.

4. The film of claim 3 wherein the low density polyethylene is linear low density polyethylene.

5. The film of claim 1 wherein the core layer comprises a color pigment.

6. The film of claim 5 wherein the color pigment is titanium dioxide.

7. The film of claim 5 wherein the core layer comprises 57% by weight polyethylene and 43% by weight color pigment.

8. The film of claim 7 wherein the polyethylene is low density polyethylene and the color pigment is titanium dioxide.

9. The film of claim 1 further comprising:

a tie layer disposed between the print layer and the core layer.

10. A film for printing comprising:

a print layer comprising a plurality of sublayers wherein each sublayer independently comprises a blend of at least one high absorption capacity material selected from the group consisting of poly(methyl methacrylate), modified poly(methyl methacrylate), impact modified polystyrene, styrene acrylic copolymer, styrene-olefin copolymer, styrene-acrylic-olefin copolymer, acrylonitrile butadinene styrene polymer, styrene acrylonitrile polymer, and copolyester polymer; and at least one low absorption capacity material, wherein the at least one low absorption material comprises an olefin polymer, and wherein an absorption gradient is present between at least two adjacent sublayers of the plurality of sublayers comprising the printing layer;

a core layer;

an adhesive layer;

wherein the core layer is between the print layer and the adhesive layer;

wherein the core layer comprises at least one polyolefin.

11. The film of claim 10 wherein the polyolefin of the core layer is polyethylene.

12. The film of claim 11 wherein the polyethylene is selected from the group consisting of low density polyethylene, medium density polyethylene, and high density polyethylene.

13. The film of claim 12 wherein the low density polyethylene is linear low density polyethylene.

14. The film of claim 10 wherein the core layer comprises a color pigment.

15. The film of claim 14 wherein the color pigment is titanium dioxide.

16. The film of claim 14 wherein the core layer comprises 57% by weight polyethylene and 43% by weight color pigment.

17. The film of claim 16 wherein the polyethylene is low density polyethylene and the color pigment is titanium dioxide.

18. The film of claim 10 further comprising:

a tie layer disposed between the print layer and the core layer.

19. A film for printing comprising a printing layer, a core layer, and an adhesive layer, wherein the core layer is between the printing layer and the adhesive layer, and wherein the printing layer comprises a plurality of sublayers;

wherein each sublayer independently comprises a blend of at least one high absorption capacity material selected from the group consisting of poly(methyl methacrylate) and modified poly(methyl methacrylate); and at least one low absorption capacity material;

wherein the at least one low absorption material comprises one or more polyolefin polymers;

wherein an absorption gradient is present between at least two adjacent sublayers of the plurality of sublayers comprising the printing layer;

wherein the core layer comprises at least one polyolefin.

20. The film of claim 19 wherein the polyolefin is polyethylene.

21. The film of claim 20 wherein the polyethylene is selected from the group consisting of low density polyethylene, medium density polyethylene, and high density polyethylene.

22. The film of claim 21 wherein the low density polyethylene is linear low density polyethylene.

23. The film of claim 19 wherein the core layer comprises a color pigment.

24. The film of claim 23 wherein the color pigment is titanium dioxide.

25. The film of claim 23 wherein the core layer comprises 57% by weight polyethylene and 43% by weight color pigment.

26. The film of claim 25 wherein the polyethylene is low density polyethylene and the color pigment is titanium dioxide.

27. The film of claim 19 further comprising:

a tie layer disposed between the printing layer and the core layer.
