Abstract

The present disclosure is drawn to embossed print media including a media substrate having a front side and a back side, an embossed image-receiving layer formed on the front side of the media substrate at a coating weight of 3 gsm to 50 gsm, and a fabric liner coupled to the back side of media substrate via an adhesive layer. The embossed image-receiving layer can include a first pigment filler and a first polymeric binder. The adhesive layer can be applied at a coating weight from 20 gsm to 40 gsm and can include a second polymeric binder and a flame-retarding filler.

First claim

What is claimed is:

1. An embossed print medium, comprising:
a media substrate having a front side and a back side;
an embossed image-receiving layer formed on the front side of the media substrate at a coating weight of 3 gsm to 50 gsm, wherein the embossed surface has a surface roughness greater than 5 μm, wherein the image-receiving layer comprises a first pigment filler, and a first polymeric binder;
an abrasion-resistant layer applied to the embossed image-receiving layer at a coating weight of from 3 gsm to 50 gsm, wherein the abrasion-resistant layer comprises a second pigment filler and a cross-linked polymer network comprising an epoxy; and
a fabric liner applied to the back side of the media substrate with an adhesive layer directly coupling the media substrate to the fabric liner, wherein the adhesive layer has a coating weight of from 20 gsm to 40 gsm, and wherein the adhesive layer comprises a second polymeric binder and a flame-retarding filler.

2. The embossed print medium of claim 1 , wherein the cross-linked polymer network further comprises a polyurethane.

3. The embossed print medium of claim 1 , wherein the media substrate comprises a polymeric latex.

4. The embossed print medium of claim 1 , wherein the first polymeric binder has a weight average molecular weight greater than 10,000 Mw.

5. The embossed print medium of claim 1 , wherein the fabric liner comprises from 20 wt % to 90 wt % synthetic fibers and from 10 wt % to 80 wt % natural fibers.

6. The embossed print medium of claim 1 , wherein the flame-retarding filler comprises a mineral powder selected from aluminum hydroxide, magnesium hydroxide, huntite, hydromagnesite, hydrates, red phosphorus, boehmite, borates, or combinations thereof.

7. The embossed print medium of claim 1 , wherein the embossed print medium is stretchable in one direction by 5% without tearing or cracking.

8. The embossed print medium of claim 1 , wherein the embossed surface has a surface roughness from greater than 5 μm to about 15 μm.

9. The embossed print medium of claim 1 , wherein the image-receiving layer is embossed to have the appearance of canvas.

10. The embossed print medium of claim 1 , wherein the media substrate is a polymeric film.
