Hot stamping glass
First Claim

1. A method of decorating a glass substrate with hot stamping foil consisting essentially of:
- a) applying a radiation curable adhesive ink to the glass substrate in a predetermined design that leaves some areas of the glass ink-free, said ink being operable, when cured, to bond to glass and, when heated after curing to adhere to hot stamping foil,b) curing the ink on the substrate by exposing it to the radiation by which it is curable, thereby bonding the ink design to the glass;
c) pressing a sheet of hot stamping foil against the substrate with a compress heated to a temperature sufficient to cause the foil to adhere to the heated, cured ink design but not to the ink-free areas of the glass; and
d) peeling the foil away from the substrate, thereby leaving behind a portion of the foil adhered to the adhesive ink design.

15. A method for decorating a glass substrate containing a decorated and nondecorated portion consisting essentially of:
-
a) painting a decoration on a glass substrate using a radiation curable adhesive ink, b) curing the adhesive ink, c) compressing a layer of hot stamping foil against the glass with a compress heated to at least 250°
F.,d) whereby foil becomes adhesively adhered to the decoration but does not adhere to the nondecorated areas of the glass substrate; e) removing the foil which is not adhered to the nondecorated glass substrate, to obtain a glass substrate where foil remains adhered only to the decoration. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of decorating a glass substrate consisting essentially of:
-
a) applying a radiation curable adhesive ink in a predetermined design that leaves some areas of the glass ink-free, said ink being operable when cured to bond to glass and, after curing, to adhere to the hot melt adhesive layer of hot stamping foil that is a multilayer web comprised of a backing film carrier, a release coating, protective top coating, and a hot melt adhesive, in that order; b) curing the ink on the substrate thereby bonding the ink design to the glass; c) compressing a sheet of said hot stamping foil against the substrate with the hot melt adhesive layer being in contact with the substrate, using pressing means heated to a temperature sufficient to cause the hot melt adhesive layer to bond to the heated, cured ink design but not to the ink-free areas of the glass and to cause the release coating to release the backing film carrier in those locations where the hot melt adhesive bonds to the ink design; and d) peeling the foil away from the substrate thereby leaving on the substrate only the portion of the foil that has bonded to the adhesive ink design.
