Abstract

A printable media comprising a supporting substrate, including fibers, having an image side and a non-image side, which contains an image receiving layer coated on the image side of the supporting substrate. The image receiving layer comprises pigment fillers, polymeric binders and ink optical density enhancement agents. Also disclosed is a method for producing the textured media.

First claim

The invention claimed is:

1. A printable media comprising:
a. a supporting substrate, with an image side and a non-image side, including fibers;
b. and, at least, an image receiving layer coated on the image side of the supporting substrate comprising pigment fillers, polymeric binders and ink optical density enhancement agents, wherein the image receiving layer comprises a polymeric network and poly-alkene polymeric compounds.

2. The printable media of claim 1 wherein the supporting substrate contains a synthetic polymeric fiber as a first constituent material and a natural fiber as a second constituent material.

3. The printable media of claim 1 wherein the supporting substrate comprises particulate inorganic substances.

4. The printable media of claim 1 wherein the supporting substrate is a polymeric film substrate.

5. The printable media of claim 1 wherein, in the image receiving layer, the ink optical density enhancement agent comprises, at least, an ionene compound.

6. The printable media of claim 5 wherein the ionene compound is a cationic charged polymer.

7. The printable media of claim 5 wherein the ionene compound is a cationic gelatin, cationic dextran, cationic chitosan, cationic cellulose, cationic cyclodextrin, carboxy-methyl chitosan, N, N, N -trimethyl chitosan chloride, alkoxylated quaternary polyamines, polyamines, polyamine salts, polyacrylate diamines, quaternary ammonium salts, polyoxyethylenated amines, quaternized polyoxyethylenated amines, poly-dicyandiamide, poly-diallyl-dimethyl ammonium chloride polymeric salt, quaternized dimethylaminoethyl(meth)acrylate polymers, polyethyleneimines, branched polyethyleneimines, quaternized poly-ethylenimine, polyurias, poly[bis(2-chloroethyl)ether-alt-1,3bis[3-(dimethylamino)propyl]urea], quaternized poly[bis(2-chloroethyl)ether-alt-1,3-bis[3-(dimethylamino)propyl], vinyl polymers or salts thereof, quaternized vinyl-imidazol polymers, modified cationic vinyl alcohol polymers, alkyl-guanidine polymers, or a combination thereof.

8. The printable media of claim 1 wherein, in the image receiving layer, the ink optical density enhancement agent is present in an amount representing from about 5 to about 10 parts per 100 parts by total dry weight of the coating components present in the image receiving layer.

9. The printable media of claim 1 wherein the polymeric network is formed by using self-cross linked polyurethane polymers or cross-linkable polyglycidyl or polyoxirane resins.

10. The printable media of claim 1 wherein the poly-alkene polymeric compounds are polytetrafluoroethylenes, polyamide or polyethylene polymer compounds.

11. The printable media of claim 1 that comprises a barrier layer that is deposited over the supporting substrate on the non-image side of the media.

12. The printable media of claim 1 wherein the supporting substrate and the image receiving layer form a textured surface on the image side of the printable media.

13. Method for forming the printable media of claim 1 comprising:
a. providing the supporting substrate, with the image side and the non-image side, including the fibers;
b. providing an image receiving layer composition by adding ink optical density enhancement agents into a mixture of pigment fillers and polymeric binders;
c. coating the image receiving layer composition on the image side of the supporting substrate to form an image receiving layer;
d. drying the coating layer under heat to form the printable media.

14. The method of claim 13 wherein the supporting substrate and the image receiving layer are embossed in order to obtain textured surfaces on the image side of the printable media.

15. The method of claim 13 wherein the supporting substrate contains a synthetic polymeric fiber as a first constituent material and a natural fiber as a second constituent material, or the supporting substrate comprises particulate inorganic substances, or the supporting substrate is a polymeric film substrate.

16. The method of claim 13 wherein, in the image receiving layer, the ink optical density enhancement agent comprises, at least, an ionene compound.

17. The method of claim 16 wherein the ionene compound is a cationic gelatin, cationic dextran, cationic chitosan, cationic cellulose, cationic cyclodextrin, carboxy-methyl chitosan, N, N, N -trimethyl chitosan chloride, alkoxylated quaternary polyamines, polyamines, polyamine salts, polyacrylate diamines, quaternary ammonium salts, polyoxyethylenated amines, quaternized polyoxyethylenated amines, poly-dicyandiamide, poly-diallyl-dimethyl ammonium chloride polymeric salt, quaternized dimethylaminoethyl(meth)acrylate polymers, polyethyleneimines, branched polyethyleneimines, quaternized poly-ethylenimine, polyurias, poly[bis(2-chloroethyl)ether-alt-1,3bis[3-(dimethylamino)propyl]urea], quaternized poly[bis(2-chloroethyl) ether-alt-1,3-bis[3-(dimethylamino)propyl], vinyl polymers or salts thereof, quaternized vinyl-imidazol polymers, modified cationic vinyl alcohol polymers, alkyl-guanidine polymers, or a combination thereof.

18. The method of claim 13 wherein, in the image receiving layer, the ink optical density enhancement agent is present in an amount representing from about 5 to about 10 parts per 100 parts by total dry weight of the coating components present in the image receiving layer.

19. The method of claim 13 further comprising depositing a barrier layer over the supporting substrate on the non-image side of the media.
