| abstract |
A method for decorating a vitreous substrate with a radiation curable ink composition, comprising applying an ink composition comprised of an N-vinyl lactam to the glass in a predetermined design, the ink being operable when cured to bond to the vitreous substrate, curing the ink on the vitreous substrate by exposing it to the radiation by which it is curable, thereby bonding the ink composition to the substrate; and a method for decorating a vitreous substrate with hot stamping foil comprising applying an ink composition comprised of an N-vinyl lactam to the glass in a predetermined design, the ink being operable when cured to bond to the vitreous substrate, curing the ink on the vitreous substrate by exposing it to the radiation by which it is curable, thereby bonding the ink composition to the substrate, pressing a sheet of hot stamping foil against the substrate with a die heated to a temperature sufficient to cause a portion of the hot stamping foil to adhere to the heated, cured, ink design but not to the ink free areas of the vitreous substrate, removing the die, thereby leaving behind a portion of the foil adhered to the ink design but not to the ink-free areas of the glass. |
