ENVIRONMENTALLY FRIENDLY, SOLVENT-FREE PRINTING INK AND USE THEREOF

摘要

The invention relates to an environmentally friendly, solvent-free printing ink, particular for printing single-pane safety glass, and also to its use in the form of a process for producing this printing, for example as an alternative way of achieving an in-line coloration of flat glass.;The problem addressed by this invention, that of providing an environmentally-friendly, solvent-free printing ink, in particular for colored printing of a substrate, for example glass/single-pane safety glass, and also the use of this printing ink which avoids the disadvantages of the prior art is solved by the presence of a pigmented system in a lacquer slurry, the printing ink being water soluble and digitally printable, so that a process for producing a coating on glass using this printing ink comprising the steps ofcleaning the glass surface (in glass washing system or manually by using special cleaner [comprising acetic acid])pretreating the glass surface in a flame pyrolysis process to generate an SiO_x layer (addition of siloxanes into the flame)applying an adhesion-promoting primer (primer) by air brush (adhesion promoter based on isopropanol and comprising silane as adhesion-promoting component)flushing the primer layer off (for about 5 min in the example)preparing the printed image with the invention's CPS by means of a commercial digital ink jet processcuring the CPS by means of infrared,is made possible.
