Abstract: A glass printing ink and a glass printing lacquer comprising at least one pigment, at least one photoinitiator, at least two resins and radicial photoinitiators. One resin is an epoxy resin having an average molecular weight based on bisphenol A, diluted in a UV hardening monomer. The other resin is a resin which contains free functional amino, hydroxy, epoxy, acid, acid anhydride and/or acrylate groups. Also, the use of the glass printing ink and glass printing lacquer when printing a glass substrate and to a method for printing a glass substrate.

Abstract: A glass printing ink and glass printing lacquer are prepared, which contain at least one photoinitiator, at least one resin and at least one additional substance. The resin is an epoxy resin based on bisphenol A, diluted in a UV-curing monomer, or a resin with functional groups containing free functional amino, hydroxy, epoxy, acid, acid anhydride and/or acrylate groups, or a combination of the epoxy resin with the resin with functional groups. The at least one additional substance is a wax. The use of the glass printing ink and glass printing lacquer in printing a glass substrate and processes for the printing of a glass substrate are also described.
