Abstract

A printable glitter paper includes a first adhesive layer onto which glitter has been deposited, and a second adhesive layer covering the first adhesive layer and glitter. A coating covers the second adhesive layer. Another adhesive layer covers the back side of the printable glitter paper. The printable glitter paper provides excellent retention of the glitter, and a high level of smoothness for high quality printing.

Claims (64)

1. A printable medium, comprising:

a flat, flexible substrate having a front surface and a back surface;

a first adhesive layer covering a portion of the front surface of the substrate;

a plurality of glitter flakes dispersed across substantially all of the first adhesive layer; and

a second adhesive layer covering substantially all of the first adhesive layer and glitter flakes, wherein the second adhesive layer is formed from a water based glue consisting of water, styrene, acrylic acid, and butyl acrylate.

2. The printable medium of claim 1 , wherein the first adhesive layer is formed from an oil-based glue.

3. The printable medium of claim 2 , wherein the oil-based glue includes polyester polyol, isocyanate, and solvents.

4. The printable medium of claim 1 , wherein the first adhesive layer covers substantially all of the front surface of the substrate.

5. A printable medium, comprising:

a flat, flexible substrate having a front surface and a back surface;

a first adhesive coating covering a portion of the front surface of the substrate;

a plurality of glitter flakes dispersed across substantially all of the first adhesive coating;

a second adhesive coating covering substantially all of the first adhesive coating and glitter flakes; and

a top coating covering substantially all the second adhesive coating, the top coating comprising silica gel, glycerol, polyethylene, a drying agent, A20 Aluminum powder, a fixative, and a thickener.

6. A printable medium, comprising:

a flat, flexible substrate having a front surface and a back surface;

a first adhesive coating covering a portion of the front surface of the substrate;

a plurality of glitter flakes dispersed across substantially all of the first adhesive coating;

a second adhesive coating covering substantially all of the first adhesive coating and glitter flakes; and

a back adhesive layer covering substantially all of the back surface of the substrate.

7. The printable medium of claim 6 , wherein the back adhesive layer is formed from a water-based glue.

8. The printable medium of claim 7 , wherein the water based glue includes water, styrene, acrylic acid, and butyl acrylate.

9. A method of making a printable medium, comprising:

providing a flat, flexible substrate having a front surface and a back surface;

applying a first adhesive layer to a portion of the front surface of the substrate;

applying a plurality of glitter flakes across substantially all of the first adhesive layer;

applying a second adhesive layer to substantially all of the first adhesive layer and glitter flakes, wherein the second adhesive layer is formed from a water based glue consisting of water, styrene, acrylic acid, and butyl acrylate; and

applying heat to the substrate, first adhesive layer, and second adhesive layer.

10. The method of claim 9 , wherein the first adhesive layer is funned, from an oil-based glue.

11. The method of claim 10 , wherein the oil-based resin includes polyester polyol, isocyanate, and solvents.

12. The method of claim 9 , wherein the step of applying heat to the substrate, first adhesive coating, and second adhesive coating is performed at a temperature of about 130° C. to about 160° C.

13. A method of making a printable medium, comprising:

providing a flat, flexible substrate having a front surface and a back surface;

applying a first adhesive coating to a portion of the front surface of the substrate;

applying a plurality of glitter flakes across substantially all of the first adhesive coating;

applying a second adhesive coating to substantially all of the first adhesive coating and glitter flakes;

applying heat to the substrate, first adhesive coating, and second adhesive coating;

applying, pressure at a first pressure level to the substrate, first adhesive coating, and second adhesive coating;

applying a top coating covering substantially all of the second adhesive coating, the top coating comprising water, silica gel, glycerol, polyethylene, a drying agent, A20 Aluminum powder, a fixative, and a thickener;

applying heat to the substrate, first adhesive coating, second adhesive coating, and top coating; and

applying pressure at a second pressure level to the substrate, first adhesive coating, second adhesive coating, and top coating.

14. The method of claim 13 , wherein the first pressure level is higher than the second pressure level.

15. The method of claim 13 , wherein the first pressure level is about 10 MPa to about 11 MPa of pressure.

16. The method of claim 13 , wherein the second pressure level is about 1 MPa.

17. The method of claim 13 , wherein the step of applying heat to the substrate, first adhesive coating, second adhesive coating, and top coating is performed at a temperature of about 130° C. to about 160° C.

18. The method of claim 13 , further comprising applying steam to the back surface of the substrate.

19. A method of making a printable medium, comprising:

providing a flat, flexible substrate having a front surface and a back surface;

applying a first adhesive layer to a portion of the front surface of the substrate;

applying a plurality of glitter flakes across substantially all of the first adhesive layer;

applying a second adhesive layer to substantially all of the first adhesive layer and glitter flakes;

applying heat to the substrate, first adhesive layer, and second adhesive layer; and

providing a back adhesive layer covering substantially all of the back surface of the substrate.

20. The method of claim 19 , wherein the back adhesive layer is formed from a water-based glue.

21. The method of claim 20 , wherein the water based glue includes water, styrene, acrylic acid, and butyl acrylate.

22. A top coating composition for a printable medium, the top coating comprising water, silica gel, glycerol, polyethylene, a drying agent, A20 Aluminum powder, a fixative, and a thickener.

23. The top coating composition according to claim 22 , wherein the top coating comprises about 41.2% water, about 45.47% silica gel, about 0.7% glycerol, about 7.1% polyethylene, about 1.3% drying agent, about 0.9% A20 Aluminum powder, about 2.6% fixative, and about 0.73% thickener.

24. A method of making a top coating composition for a printable medium, the method comprising:

mixing water and silica gel at about 5,000 r.p.m. for about 1.5 hours;

adding glycerol, and mixing the resulting combination for about 20 minutes at about 5,000 r.p.m;

adding polyethylene and a drying agent; and mixing the resulting combination for about 30 minutes at about 5,000 r.p.m;

adding A20 Aluminum powder, and mixing the resulting combination at about 5,000 r.p.m. for about 30 minutes;
