Abstract

The present disclosure relates to a decorative panel made of flat glass for electronic household appliances, in particular, for large stationary household appliances. The decorative panel comprises a base body made of thermally tempered flat glass with an operational front and an operational back and has at least one digital print on the operational back.

First claim

What is claimed is:

1. A decorative panel, comprising:
a base body made of thermally tempered flat glass, wherein the base body has an operational front and an operational back;
at least one digital print on the operational back, wherein the at least one digital print on the operational back contains organic molecules; and
at least one indentation on the operational front of the decorative panel, wherein the at least one indentation has an additional digital print therein.

2. The decorative panel according to claim 1 , wherein the organic molecules are crosslinked or polymerized organic molecules.

3. The decorative panel according to claim 1 , wherein the digital print on the decorative panel has a cross-cut rating of 0 or 1 according to DIN EN ISO 2409 after storing the printed decorative panel in distilled water for 24 hours at room temperature.

4. The decorative panel according to claim 1 , wherein the decorative panel does not have an adhesion-promoting layer between the base body and the digital print.

5. The decorative panel according to claim 1 , wherein the base body is composed of soda-lime glass.

6. The decorative panel according to claim 1 , wherein the base body has a thickness of 2 mm to 8 mm.

7. The decorative panel according to claim 1 , wherein the base body has a thickness of 3 mm to 6 mm.

8. The decorative panel according to claim 1 , wherein the decorative panel comprises, in addition to the digital print, at least one print or coating on the operational front or back that contains inorganic pigments.

9. A decorative panel, comprising:
a base body made of thermally tempered flat glass, wherein the base body has an operational front and an operational back;
at least one digital print on the operational back, wherein the digital print contains organic molecules; and
at least one raised region of at least 250 μm height on the operational front of the decorative panel, wherein at least one region outside the raised region has an additional digital print on the operational front.

10. The decorative panel according to claim 1 , wherein the decorative panel has a coating that protects against thermal, chemical or mechanical effects.

11. The decorative panel according to claim 1 , wherein the digital print is electrically conductive.

12. The decorative panel according to claim 1 , further comprising a transparent adhesion-promoting layer between the base body and the digital print.

13. A decorative panel, comprising:
a base body made of thermally tempered flat glass, wherein the base body has an operational front and an operational back; and
at least one digital print on the operational back, wherein the digital print contains organic molecules,
wherein the at least one digital print has an optical density of more than 3 in the wavelength region from 380 to 780 nm.

14. A decorative panel, comprising:
a base body made of thermally tempered flat glass, wherein the base body has an operational front and an operational back; and
at least one digital print on the operational back, wherein the digital print contains organic molecules,
wherein the at least one digital print is composed of at least two layers arranged one behind the other and each having an optical density of less than 2 between 380 and 780 nm.

15. A decorative panel, comprising:
a base body made of thermally tempered flat glass, wherein the base body has an operational front and an operational back; and
at least one digital print on the operational back, wherein the digital print contains organic molecules
wherein the at least one digital print is composed of at least two layers, at least one layer of which has a recess, and at least one other layer has an optical density between 380 and 780 nm, at least in the region of the recess, that is lower than the optical density of the first layer at a place outside the recessed region.

16. A electronic household appliance comprising the decorative panel of claim 1 as a control panel or outer door glazing.
