Environmentally friendly, solvent-free printing ink and use thereof

This invention is about a special, eco-friendly printing ink that doesn't use solvents and can be printed digitally, especially on glass. It's made from a water-based mixture of very fine pigment powder that hardens through a chemical reaction. The specific version protected by the claims uses a powder containing polyester epoxide, designed to work with inkjet printers.

Why it matters: The focus on "environmentally friendly" and "solvent-free" solutions has intensified significantly since 2007, aligning better with current regulatory and consumer demands. Industrial digital inkjet printing and infrared curing technologies have also matured, making the precise application and efficient curing of such specialized inks on glass more practical for in-line production.
