Semi-transparent coating material

A semi-transparent coating material for coating glass or glass ceramics comprising:

• at least one sol-gel hybrid-polymer coating system having a hybrid-polymer or inorganic sol-gel-based matrix, and
• nanoparticles and nanoscale pigments and/or dyes are added to the hybrid-polymer or inorganic sol-gel-based matrix.

A semi-transparent coating material for coating glass or glass ceramics comprising:

• a mixture of a first component mixture and a second component mixture as a screen-printable 2-component coating based on hybrid polymer, whereby the first component mixture has the hybrid polymer and the second component mixture has nanoparticles, and the first and/or the second component mixture has nanoscale pigments and/or dyes.

The coating material according to claim 33, wherein the semi-transparent coating has a transmittance in the visible wavelength region between 2 and 15%.

A method for applying a semi-transparent coating material for coating glass or glass ceramics comprising at least one sol-gel hybrid-polymer coating system having a hybrid-polymer or inorganic sol-gel-based matrix, and nanoparticles and nanoscale pigments and/or dyes are added to the hybrid-polymer or inorganic sol-gel-based matrix, or a semi-transparent coating material for coating glass or glass ceramics comprising a mixture of a first component mixture and a second component mixture as a screen-printable 2-component coating based on hybrid polymer, whereby the first component mixture has the hybrid polymer and the second component mixture has nanoparticles, and the first and/or the second component mixture has nanoscale pigments and/or dyes, comprising coating material being applied by a printing method selected from the group consisting of ink-jet printing, offset printing, pad printing, roll coating, dipping methods, spin coating or spraying methods.
