Abstract

A process for modifying the surface of a solid substrate includes modifying the surface with at least one oxidizing flame and modifying the surface with at least one silicatising flame. The process is particularly beneficial in preparing glass and other surfaces for printing thereon.

Claims

1. A process for modifying the surface of a solid substrate;

this process comprising;

modifying the surface with at least one oxidising flame;

modifying the surface with at least one silicatising flame; and

depositing a printing ink on the surface of the solid substrate.

2. The process according to claim 1, wherein the printing ink is selected from the group consisting of a liquid, a paste, a powder, an aerosol, a spray and combinations thereof.

3. The process according to claim 1, wherein the printing ink has fillers selected from from at least one of the group consisting of calcium carbonate, aluminium oxide hydrate, barium sulphate, silicon dioxide, aluminium silicate and magnesium silicate.

4. The process according to claim 1, wherein the printing ink is deposited on the surface by a printing process selected from the group consisting of screen printing, planographic printing, offset printing, gravure printing, flexographic printing and letter printing.

5. The process according to claim 4, wherein the printing ink is selected from a group consisting of inorganic pigments, mineral pigments, metal pigments, interference pigments, carbon pigments, organic pigments, soluble organic dyestuffs and UV colorants.

6. The process according to claim 5, wherein the organic pigments are selected from the group consisting of azo pigments, isoindulin pigments, phthalocyanine pigments, special poly-cyclic pigments, pigments based on basic salts, luminescence pigments, dayglow pigments and nightglow pigments.

7. The process according to claim 4, wherein the printing ink has fillers selected from the group consisting of calcium carbonate, aluminium oxide hydrate, barium sulphate, silicon dioxide, aluminium silicate and magnesium silicate.

8. The process according to claim 1, wherein the solid substrate is selected from the group consisting of a glass, a melt, a glass-ceramic, a ceramic, a crystal and other solids that have a surface coated with at least one of the group consisting of glass, melt, glass-ceramic, ceramic and crystal.

9. The process according to claim 8, wherein the glass is selected from the group consisting of a glass sheet, a container, hollowware, a domestic glass, glass of a light bulb, a television tube, a laboratory glass, a lead crystal glass, a fibre glass, a jewellery glass, a frosted glass, a coloured glass, a decorative glass and an optical glass.

10. The process according to claim 1, wherein the solid substrate is a PET product.

11. The process according to claim 10, wherein the PET product is a bottle.

12. The process according to claim 1, wherein the solid substrate is selected from the group consisting of lime soda glass, borosilicate glass, sodium-silicate glass, silica glass and silica-free glass, and a phosphorus glass.

13. The process according to claim 12, wherein the glass is selected from the group consisting of a glass sheet, a container, hollowware, a domestic glass, glass of a light bulb, a television tube, a laboratory glass, a lead crystal glass, a fibre glass, a jewellery glass, a frosted glass, a coloured glass, a decorative glass and an optical glass.

14. A process for modifying the surface of a solid substrate;

this process comprising;

modifying the surface with at least one oxidising flame;

modifying the surface with at least one silicatising flame; and

printing on the modified surface.

15. The process according to claim 14, wherein the method comprises printing on the modified surface with a printing ink selected from the group consisting of a liquid, a paste, a powder, an aerosol, a spray and combinations thereof.

16. The process according to claim 15, wherein the printing ink has fillers selected from at least one of the group consisting of calcium carbonate, aluminium oxide hydrate, barium sulphate, silicon dioxide, aluminium silicate and magnesium silicate.

17. The process according to claim 15, wherein the printing ink is selected from a group consisting of inorganic pigments, mineral pigments, metal pigments, interference pigments, carbon pigments, organic pigments, soluble organic dyestuffs and UV colorants.

18. The process according to claim 14, wherein the method comprises printing on the surface by a process selected from the group consisting of screen printing, planographic printing, offset printing, gravure printing, flexographic printing and letter printing.

19. The process according to claim 14, wherein the solid substrate is selected from the group consisting of a glass, a melt, a glass-ceramic, a ceramic, a crystal and other solids that have a surface coated with at least one of the group consisting of glass, melt, glass-ceramic, ceramic and crystal.

20. The process according to claim 19, wherein the glass is selected from the group consisting of a glass sheet, a container, hollowware, a domestic glass, glass of a light bulb, a television tube, a laboratory glass, a lead crystal glass, a fibre glass, a jewellery glass, a frosted glass, a coloured glass, a decorative glass and an optical glass.

21. The process according to claim 14, wherein the solid substrate is a PET product.

22. A process for printing on a bottle, the process comprising:

subjecting a surface of the bottle to at least one oxidising flame;

subjecting the surface of the bottle to at least one silicatising flame; and

printing on the surface.

23. The process according to claim 22, wherein the bottle is made from glass.

24. The process according to claim 22, wherein the bottle is made from plastic.
