Abstract

A printable recording media including a supporting base substrate having, on both supporting sides, pre-coating layers containing inorganic pigments and polymeric binders, and having, at least, one top ink-receiving layer, that includes inorganic pigments and water-dispersible polymeric binders having a glass transition temperature within the range of about 0° C. to about 35° C., over the pre-coating layer. 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

1 ) A printable recording media comprising a supporting base substrate and having:
a. pre-coating layers, containing inorganic pigments and polymeric binders, that are applied to both sides of the supporting base substrate; b. and, at least, one top ink-receiving layer, including inorganic pigments and water-dispersible polymeric binders having a glass transition temperature within the range of about 0° C. to about 35° C., that is applied over said pre-coating layer.

2 ) The printable recording media according to claim 1 wherein top ink-receiving layers are applied to both sides of the supporting base substrate.

3 ) The printable recording media according to claim 1 wherein the coat weight of the top ink-receiving layer is ranging from about 5 to about 35 gsm.

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

5 ) The printable recording media according to claim 1 wherein the water-dispersible polymeric binders, in the top ink-receiving layer, are styrene-butadiene copolymer latex.

6 ) The printable recording media according to claim 1 wherein the inorganic pigments are present in the top ink-receiving layer in an amount representing from about 50% to about 90% of the total weight of said layer.

7 ) The printable recording media according to claim 1 wherein the top ink-receiving layer further includes non-film forming polymers.

8 ) The printable recording media according to claim 1 wherein the coat weight of the pre-coating layer is ranging from about 2 to about 25 gsm.

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

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 having a supporting base substrate, pre-coating layers, containing inorganic pigments and polymeric binders, that are applied to both sides of the supporting base substrate; and, at least, one top ink-receiving layer, including inorganic pigments and water-dispersible polymeric binders having a glass transition temperature within the range of about 0° C. to about 35° C., applied over the pre-coating layer; b. applying an ink composition on, at least, one side of the printable media, to form a printed image; c. and applying a post-image lamination film over the printed image.

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 having a supporting base substrate, pre-coating layers, containing inorganic pigments and polymeric binders, that are applied to both sides of the supporting base substrate; and, at least, one top ink-receiving layer, including inorganic pigments and water-dispersible polymeric binders having a glass transition temperature within the range of about 0° C. to about 35° C., applied over the pre-coating layer;
b. a printed feature applied on top of said printable recording media;
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 pre-coating layers containing inorganic pigments and polymeric binders on both sides of the supporting base substrate; c. applying, over said pre-coating layer, at least one top ink-receiving layer that includes inorganic pigments and water-dispersible polymeric binders having a glass transition temperature within the range of about 0° C. to about 35° C.; d. and drying and calendaring said layers.
