Abstract

A method for producing laminated safety glass includes the steps of applying imagewise a thermally reducible composition including a organic metal salt on a glass surface or a thermoplastic polymeric surface, and heating at least the imagewise applied thermally reducible composition to form a metal from the organic metal salt.

First claim

The invention claimed is:

1. A method for manufacturing laminated safety glass comprising the steps of:
applying imagewise a thermally reducible composition including an organic metal salt on a surface selected from the group consisting of a glass surface and a thermoplastic polymeric surface;
heating at least the imagewise applied thermally reducible composition to form a metal from the organic metal salt; and
during the heating step, laminating an assembly including, in order, an inner glass layer, an interlayer including the thermoplastic polymeric surface, and an outer glass layer; wherein
the organic metal salt is dispersed in the thermally reducible composition;
the thermally reducible composition does not contain a colorant; and
the thermally reducible composition is in direct contact with the thermoplastic polymeric surface of the interlayer.

2. The method according to claim 1 , wherein the step of applying imagewise the thermally reducible composition includes applying the thermally reducible composition by inkjet printing.

3. The method according to claim 1 , wherein the organic metal salt is an organic silver salt.

4. The method according to claim 3 , wherein the organic silver salt is selected from the group consisting of silver behenate, silver stearate, silver palmitate, silver laurate, or mixtures therewith.

5. The method according to claim 3 , wherein the thermally reducible composition includes silver halide.

6. The method according to claim 1 , wherein the thermally reducible composition includes a tone modifying agent selected from the group consisting of succinimides, phthalimides, phthalazinones, combinations of phtalazines and one or more phthalic acid derivatives, pyridazones, benzoxazine diones, and naphthoxazine diones.

7. The method according to claim 1 , wherein the thermally reducible composition includes a polyvinylbutyral.

8. The method according to claim 1 , wherein the thermoplastic polymeric surface is selected from the group consisting of a polyvinylbutyral surface, a poly(ethylene-co-vinyl acetate) surface, and a thermoplastic polyurethane surface.

9. The method according to claim 1 , wherein the thermally reducible composition is applied on the glass surface of the inner glass layer or the outer glass layer that makes contact with the interlayer.
