Abstract

A method for printing ink on a substrate comprising the steps of coating a glass substrate with an adhesion promoter, depositing one or more layers of ink on the coated substrate, and laminating the imaged substrate. The substrate can be a glass substrate, and the adhesion promoter can include a silane material, powder coating, organophosphate primer suspended in isopropanol.

First claim

We claim:

1. A method for printing ink on a glass substrate comprising the steps of:
pretreating a glass substrate with an organophosphate primer suspended in a solvent;
depositing one or more layers of ink on a first surface of the pretreated glass substrate; and
laminating a film onto to the first surface to form an imaged laminate.

2. The method of claim 1 , wherein the film comprises an anti-splinter film and is white or colored.

3. The method of claim 1 , wherein the film is selected from the group consisting of vinyl, polypropylene, high density polyethylene (HDPE), polyvinyl chloride (PVC), clear or cloudy polyethylene terephthalate (PET), metallized polyester, lenticular plastic and polymer dispersed liquid crystals (PDLC).

4. The method of claim 1 , further comprising the step of coating portions or all of the imaged laminate with a polymeric material.

5. The method of claim 1 , wherein the glass substrate comprises a chemically strengthened glass substrate, or a non-chemically strengthened glass substrate.

6. The method of claim 1 , wherein the step of pretreating a substrate further comprises soaking or dipping the substrate in the organophosphate primer, removing the primer, and drying the primed substrate.

7. The method of claim 4 , further comprising curing the coated portions of the imaged laminate.
