Abstract

A printable recording media including a supporting base substrate having, on its image side, a pre-coating layer that contains inorganic pigments and polymeric binders, and a top ink-receiving layer that includes inorganic pigments, polymeric binders and non-film forming polymers; and, having a polymer barrier layer on its backside. Also described herein is a method for making the printable recording media, a method for forming printed articles, and the obtained printed articles.

First claim

The invention claimed is:

1. A printable recording media comprising a supporting base substrate having:
a. on its image side,
i. a pre-coating layer that contains inorganic pigments and polymeric binders,
ii. and a top ink-receiving layer that includes inorganic pigments, polymeric binders and non-film forming polymers, wherein a weight ratio of non-film forming polymer to inorganic pigments in the top ink-receiving layer is from 1:100 to 1:10;

b. and having a polymer barrier layer on its backside.

2. The printable recording media according to claim 1 wherein the pre-coating layer is also applied on the backside of the supporting base substrate, below the polymer barrier layer.

3. The printable recording media according to claim 1 wherein the polymeric binders, present in the top ink-receiving layer and in the pre-coating layer, are latex binders selected from the group consisting of polybutadiene latex, styrene-butadiene copolymer latex, acrylonitrile-butadiene-styrene terpolymer latex, polychloroprene latex, acrylic latex, polyester emulsions, acrylonitrile-butadiene latex, polyvinyl acetate and polyvinyl acetate copolymers.

4. The printable recording media according to claim 1 wherein the polymeric binders, present in the top ink-receiving layer and in the pre-coating layer, are styrene-butadiene copolymer latex.

5. The printable recording media according to claim 1 wherein the polymeric binders, in the top ink-receiving layer, are water-dispersible binders and are present in an amount representing from about 10 wt % to about 30 wt % of the total weight of the layer.

6. The printable recording media according to claim 1 wherein the polymeric binders, in the top ink-receiving layer , are water-dispersible polymeric binders and have a glass transition temperature (Tg) within the range of about 0° C. to about 35° C.

7. The printable recording media according to claim 1 wherein the polymeric binders, in the pre-coating layer, are polyvinylalcohol or copolymer of vinylpyrrolidone.

8. The printable recording media according to claim 1 wherein the non-film forming polymers, present in the top ink-receiving layer, have a glass transition temperature (Tg) which is above about 70° C.

9. The printable recording media according to claim 1 wherein the non-film forming polymers, present in the top ink-receiving layer, are chosen among the group consisting of styrene, acrylic, styrene/acrylics, vinyl/acetate, polyacrylics, methacrylates and combinations thereof.

10. The printable recording media according to claim 1 wherein a post-image lamination film is disposed over the top ink-receiving layer after an ink layer is printed.

11. The printable recording media according to claim 10 wherein the post-image lamination film is made of a polyester material or of a polypropylene composition.

12. A method for forming printed articles comprising:
a. obtaining a printable recording media comprising a supporting base substrate having, on its image side, a pre-coating layer that contains inorganic pigments and polymeric binders, and a top ink-receiving layer that includes inorganic pigments, polymeric binders and non-film forming polymers, wherein a weight ratio of non-film forming polymer to inorganic pigments in the top ink-receiving layer is from 1:100 to 1:10; and, having a polymer barrier layer on its backside;
b. applying an ink composition on the image side of the printable media, to form a printed image;
c. and applying a post-image lamination film.

13. The method for forming printed articles according to claim 12 wherein the ink composition is a liquid electrophotographic ink.

14. A printed article obtained according to the method of claim 12 comprising:
a. a printable recording media with a supporting base substrate having, on its image side, a pre-coating layer that contains inorganic pigments and polymeric binders, and a top ink-receiving layer that includes inorganic pigments, polymeric binders and non-film forming polymers, wherein a weight ratio of non-film forming polymer to inorganic pigments in the top ink-receiving layer is from 1:100 to 1:10; and, having a polymer barrier layer on its backside;
b. a printed feature applied on top of said printable recording material, on its image side;
c. and a post-image lamination film disposed above said printed feature.

15. A method for making a printable recording material comprising:
a. providing a supporting base substrate;
b. applying a pre-coating layer that contains inorganic pigments and polymeric binders on the raw base substrate on the image side of the supporting base substrate;
c. applying a top ink-receiving layer, that includes inorganic pigments, polymeric binders and non-film forming polymers, over said pre-coating layer, wherein a weight ratio of non-film forming polymer to inorganic pigments in the top ink-receiving layer is from 1:100 to 1:10;
d. drying and calendaring said pre-coating layer and top ink-receiving layer;
e. and extruding a polymer barrier layer on the backside of the supporting base substrate.

16. The printable recording media according to claim 1 , wherein the polymer barrier layer comprises a blend of high density polyethylene and low density polyethylene.

17. The printable recording media according to claim 16 , wherein a weight ratio of high density polyethylene to low density polyethylene in the barrier layer is from 30:70 to 70:30.

18. The printable recording media according to claim 1 , wherein the polymer barrier layer has a coat weight from about 10 gsm to about 60 gsm.
