Abstract

A printable medium with a printable medium comprising a composite supporting substrate having a first fabric layer and a second layer containing fibers laminated to the first layer; an image receiving layer coated on the second layer; and an external layer, coated over the image receiving layer, comprising, at least, two polymeric networks and polymeric particles. Also disclosed are the method for making such printable medium and the method for producing printed images.

First claim

The invention claimed is:

1. A printable medium comprising:
a. a composite supporting substrate comprising:
i. a first fabric layer; and
ii. a second layer, containing fibers, laminated to the first layer,

b. an image receiving layer coated on the second layer;
c. and an external layer, coated over the image receiving layer, comprising, at least, two polymeric networks and polymeric particles.

2. The printable medium of claim 1 wherein the first fabric layer of the composite supporting substrate comprises natural fibers and synthetic fibers in a woven structure and wherein the amount of natural fibers is about 10% of a total fiber amount and the amount of synthetic fibers is about 90% of the total fiber amount.

3. The printable medium of claim 1 wherein the second layer contains a synthetic polymeric fiber as a first constituent material and a natural cellulose fiber as a second constituent material, the amount of synthetic polymeric fiber in the fiber composition is within a range of about 5% to about 80% by weight of total fibers.

4. The printable medium of claim 1 wherein the composite supporting base substrate further comprise an adhesive compound laminated between the first layer and the second layer.

5. The printable medium of claim 1 wherein the composite supporting base substrate comprises a tie layer applied over the second layer containing fibers.

6. The printable medium of claim 1 wherein the image receiving layer comprises pigment fillers, polymeric binders and latex film-forming agents.

7. The printable medium of claim 1 wherein the polymeric particles of the external layer are poly-alkene compounds.

8. The printable medium of claim 1 wherein the polymeric particles of the external layer are polytetrafluoroethylene, polyamide or polyethylene polymer particles.

9. The printable medium of claim 1 wherein one polymeric network of the external layer comprises a self-cross linked polyurethane polymer.

10. The printable medium of claim 1 wherein one polymeric network of the external layer comprises vinyl-urethane hybrid copolymer or acrylic-urethane hybrid polymer.

11. The printable medium of claim 1 wherein one polymeric network of the external layer comprises cross-linkable polyglycidyl or polyoxirane resins.

12. The printable medium of claim 1 wherein one polymeric network of the external layer comprises water-based epoxy resin and water-based polyamine.

13. The printable medium of claim 1 wherein the external layer comprises a first polymeric network that comprises a self-cross linked polyurethane polymer, and a second polymeric network that is created by using cross-linkable polyglycidyl or polyoxirane resins.

14. The printable medium of claim 1 wherein, in the external layer, the ratio of the first polymeric network to the second polymeric network ranges from 1:0.05 to 1:1.

15. A method for forming a printable medium comprising:
a. providing a first fabric layer and a second layer containing fibers;
b. laminating said first layer and said second layer together to form a composite supporting base substrate;
c. coating an image receiving layer onto the second layer containing fibers;
d. and coating an external layer comprising, at least, two polymeric networks and polymeric particles, onto the image receiving layer.
