Laminated glass articles
View Patent ↗A method for manufacturing laminated glass articles includes the steps of inkjet printing an image with one or more inkjet inks on a first glass sheet; jetting and at least partially curing a curable sealing agent on three edges of the first glass sheet on the side for the inkjet printed image; aligning a second glass sheet with the first glass sheet on the side of the first glass sheet carrying the at least partially cured sealing agent and the inkjet printed image; applying a liquid curable adhesive resin composition into an interspace between the first and second glass sheets; and curing the liquid curable adhesive resin composition until a solid adhesive layer is obtained.
1. A method for manufacturing laminated glass articles comprising the steps of:
inkjet printing an image with at least one inkjet ink on a first glass sheet;
jetting and at least partially curing a curable sealing agent on at least three edges of the first glass sheet on a first side of the first glass sheet including the inkjet printed image;
aligning a second glass sheet with the first glass sheet on the first side of the first glass sheet including the at least partially cured sealing agent and the inkjet printed image;
applying a liquid curable adhesive resin composition into a space between the first glass sheet and the second glass sheet; and
curing the liquid curable adhesive resin composition until a solid adhesive layer is obtained.
2. The method according to claim 1 , further comprising the step of:
jetting a primer on a glass surface of the first glass sheet; wherein
the at least one inkjet ink is jetted on the primer.
3. The method according to claim 1 , wherein the at least one inkjet ink is jetted on a glass surface of the first glass sheet.
4. The method according to claim 1 , wherein the at least one inkjet ink includes at least one UV curable inkjet ink.
5. The method according to claim 1 , wherein the curable sealing agent is fully cured after the step of aligning the first glass sheet and the second glass sheet.
6. The method according to claim 1 , wherein the curable sealing agent includes an inorganic pigment, a color pigment, or a mixture thereof.
7. The method according to claim 1 , wherein the curable sealing agent is jetted by an inkjet printing device that also inkjet printed the at least one inkjet ink.
8. The method according to claim 1 , wherein at least one of the liquid curable adhesive resin composition, the at least one inkjet ink, and the primer includes a polyvinylacetal polymer.
9. The method according to claim 8 , wherein the polyvinylacetal polymer is a polyvinyl butyral.
10. The method according to claim 1 , further comprising the step of:
using spacing agents to control a distance between the second glass sheet and the first glass sheet.
11. The method according to claim 1 , wherein the at least one inkjet ink includes at least one free radical photoinitiator, a polyfunctional propoxylated acrylate, and a monofunctional ethoxylated methacrylate according to Formula (I):
wherein
n represents an integer of 1 to 4; and
R represents an alkyl group, alkenyl group, or alkynyl group.
12. The method according to claim 1 , wherein the image is one of a plurality of sub-images that define an original image, and the plurality of sub-images are printed on a plurality of glass sheets.
13. A laminated glass article including information and/or a decoration manufactured by the method according to claim 1 .
14. The laminated glass article according to claim 13 , wherein spacing agents are located between the second glass sheet and the first glass sheet.
15. The laminated glass article according to claim 13 , wherein no double sided tape is present between the second glass sheet and the first glass sheet.
