UV hardening glass printing ink and UV hardening glass printing lacquer and method for printing a glass substrate

摘要

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.

主权项

1. A glass printing ink or glass printing lacquer comprising:
at least two resins, which together yield a photo-hardenable mixture; and, at least one initiator, wherein a first resin of the at least two resins comprises a bisphenol A based epoxy resin, diluted in a UV hardening monomer, and a second resin of the at least two resins is selected from the group consisting of: a melamine acrylate; an acid-modified polyester acrylate and an epoxy acrylate, and, wherein each initiator in the ink or lacquer is a radical photoinitiator.
