Abstract

A method for manufacturing a bent substrate, having a masking step of forming a masking member (M) on a bent substrate ( 10 ) and forming a predetermined pattern, and a printing step of forming a print layer (P) on a surface to be printed of the bent substrate ( 10 ) including the masking member (M). It is thereby possible to perform printing on a bent substrate having a curved surface part in a productive manner and at a high printing accuracy.

First claim

The invention claimed is:

1. A method for manufacturing a bent substrate provided with a prim layer, comprising:
a masking step of forming a masking material on a bent substrate to form a predetermined pattern; and
a printing step of forming a print layer on a surface to be printed of the bent substrate provided with the masking material, and
a mask-cleaning step of cleaning an end face of the masking material after the masking step.

2. The method for manufacturing a bent substrate provided with a print layer according to claim 1 , further comprising a heating step of heating a printing material printed on the bent substrate.

3. The method for manufacturing a bent substrate provided with a print layer according to claim 1 , further comprising a step of irradiating a printing material printed on the bent substrate with UV.

4. The method for manufacturing a bent substrate provided with print layer according to claim 1 , wherein in the masking step, a printing material different from a printing material used in the printing step is printed as the masking material.

5. The method for manufacturing a bent substrate provided with a print layer according to claim 1 , wherein in the printing step, a printing material is ejected from a nozzle to be applied to the bent substrate.

6. The method for manufacturing a bent substrate provided with a print layer according to claim 1 , wherein the printing step is carried by a spraying method comprising ejecting a printing material from a nozzle to be applied to the bent substrate.

7. The method for manufacturing a bent substrate provided with a print layer according to claim 1 ,
wherein the bent substrate comprises a flat surface part and a curved surface part, and
the masking material is formed on the flat surface part.

8. The method for manufacturing a bent substrate provided with a print layer according to claim 1 , further comprising a removal step of removing the masking material formed on the bent substrate after the printing step.

9. The method for manufacturing a bent substrate provided with a print layer according to claim 8 , wherein the removal step is a step of eluting the masking material in a solvent.

10. The method for manufacturing a bent substrate provided with a print layer according to claim 8 , further comprising a step of removing an end face of the print layer after the removal step.

11. The method for manufacturing a bent substrate provided with a print layer according to claim 1 , wherein the bent substrate is fixed with a jig in at least one step of the masking step and the priming step, and the jig has a shape corresponding to the main surface of the bent substrate that contacts the jig.

12. The method for manufacturing a bent substrate provided with a print layer according to claim 1 , wherein the bent substrate is a glass.

13. A bent substrate provided with a print layer, having an angle α being an obtuse angle, wherein the angle α centers on the boundary between the print layer and a non-print surface on the bent substrate, and is formed by an end face of the print layer and a surface of the print layer that contacts a surface of the bent substrate, in a cross-sectional view along the thickness direction,
wherein the prim layer is formed on a curved surface part of the bent substrate.

14. The bent substrate provided with a grit t layer according to claim 13 , wherein the angle α is larger than 90° and 120° or smaller.

15. The bent substrate provided with a print layer according to claim 13 , wherein the following relation is satisfied,
α≥β,

wherein β is an angle formed by a tangent of an upper part of an end face of the print layer on the bent substrate and a tangent of the surface of the print layer that contacts the surface of the bent substrate, in a cross-sectional view along the thickness direction.

16. The bent substrate provided with a print layer according to claim 15 , wherein the angle β is 45° or larger and 120° or smaller.

17. The bent substrate provided with a print layer according to claim 13 , wherein the curved surface part has a radius of curvature in a range of 1 mm to 500 mm.

18. The bent substrate provided with a print layer according to claim 13 , wherein a thickness of the bent substrate is in a range 0.3 mm to 2 mm.

19. The bent substrate provided with a print layer according to claim 13 , wherein the bent substrate is an inorganic glass.
