Radiation curable etch resistant inkjet ink printing

摘要

The present invention is drawn towards methods of inkjet printing radiation curable inkjet inks forming a protective layer during an etching process, wherein the radiation curable inkjet ink includes at least 70 percent by weight of a polymerizable composition based on the total weight of radiation curable inkjet ink, wherein the polymerizable composition has an oxygen fraction OFR > 0.250 and a weighted polymerizable functionality WPF ≥ 0.0050, and wherein the polymerizable composition contains no polymerizable compound with an ethylenic double bond and including a phosphoester group or a carboxylic acid group in the molecule thereof.
