Ceramic Ink For Inkjet Digital Printing
Patent No. EP3856860 (titled "Ceramic Ink For Inkjet Digital Printing") was filed by Flooring Industries on Sep 11, 2019. The application was issued on Nov 1, 2023.
Patent Summary
A ceramic ink for inkjet digital printing comprises a solid part containing at least one ceramic component and a liquid part containing a first vehicle. The first vehicle, representing at least 10 wt% of the total ink weight, is selected from esterified terephthalates, cyclohexane dicarboxylates, citrates, trimethylolpropane esters, or fatty acid esters of aromatic alcohols. These vehicles provide suitable rheological properties and high thermal stability, degrading primarily into non-toxic, low-odor components (e.g., $\text{CO}_2$, $\text{CO}$) during high-temperature firing (above 400°C), thereby limiting VOC and aldehyde emissions compared to traditional glycol ethers or fatty acid esters. The liquid part may optionally include a second vehicle for rheology regulation, such as glycol ethers, alcohols, or hydrocarbons.
