Abstract

A glass sheet for pigment printing contains, as represented by mass percentage on the basis of oxides, from 60% to 75% of SiO2, from 2% to 12% of Al2O3, from 2% to 11% of MgO, from 0% to 10% of CaO, from 0% to 3% of SrO, from 0% to 3% of BaO, from 10% to 18% of Na2O, from 0% to 8% of K2O, and from 0% to 4% of ZrO2, or contains, from 60% to 75% of SiO2, from 1.5% to 12% of Al2O3, from 6% to 12% of MgO, from 0% to 4.5% of CaO, from 0% to 3% of SrO, from 0% to 3% of BaO, from 10% to 18% of Na2O, from 0% to 8% of K2O, and from 0% to 4% of ZrO2.

First claim

The invention claimed is:

1. A glass sheet, comprising, as represented by mass percentage on the basis of oxides, from 60% to 75% of SiO 2 , from 2% to 9% of Al 2 O 3 , from 6% to 11% of MgO, from 0% to 4.5% of CaO, from 0% to 3% of SrO, from 0% to 3% of BaO, from 10% to 18% of Na 2 O, from 0% to 2% of K 2 O, and from 0% to 4% of ZrO 2 .

2. The glass sheet according to claim 1 , having the content of Al 2 O 3 of from 3% to 9%.

3. A glass sheet, comprising, as represented by mass percentage on the basis of oxides, from 60% to 75% of SiO 2 , from 1.5% to 9% of Al 2 O 3 , from 6% to 12% of MgO, from 0% to 4.5% of CaO, from 0% to 3% of SrO, from 0% to 3% of BaO, from 10% to 18% of Na 2 O, from 0% to 2% of K 2 O, and from 0% to 4% of ZrO 2 .

4. The glass sheet according to claim 3 , having a mass ratio (CaO/MgO) of the CaO to the MgO of from 0 to 0.67.

5. The glass sheet according to claim 1 , which has been subjected to a chemical strengthening treatment.

6. The glass sheet according to claim 1 , which has been formed by a float process.

7. A pigment-printed glass sheet, comprising a glass substrate comprising, as represented by mass percentage on the basis of oxides, from 60% to 75% of SiO 2 , from 2% to 9% of Al 2 O 3 , from 6% to 11% of MgO, from 0% to 4.5% of CaO, from 0% to 3% of SrO, from 0% to 3% of BaO, from 10% to 18% of Na 2 O, from 0% to 2% of K 2 O, and from 0% to 4% of ZrO 2 , the glass substrate having a pigment being printed on at least one surface thereof.

8. A pigment-printed glass sheet according to claim 7 , comprising a glass substrate comprising, as represented by mass percentage on the basis of oxides, from 3% to 9% of Al 2 O 3 , the glass substrate having a pigment being printed on at least one surface thereof.

9. A pigment-printed glass sheet, comprising a glass substrate comprising, as represented by mass percentage on the basis of oxides, from 60% to 75% of SiO 2 , from 1.5% to 9% of Al 2 O 3 , from 6% to 12% of MgO, from 0% to 4.5% of CaO, from 0% to 3% of SrO, from 0% to 3% of BaO, from 10% to 18% of Na 2 O, from 0% to 2% of K 2 O, and from 0% to 4% of ZrO 2 , the glass substrate having a pigment being printed on at least one surface thereof.

10. The pigment-printed glass sheet according to claim 7 , wherein the glass substrate has been subjected to a chemical strengthening treatment.

11. A method for producing a pigment-printed glass sheet comprising:
preparing the glass sheet according to claim 1 ; and
printing a pigment on at least one surface of the glass sheet for pigment printing.

12. An image display device, comprising the pigment-printed glass sheet according to claim 7 .
