放射線硬化可能なエッチング抵抗性インキジェットインキ印刷

摘要

An inkjet printing radiation curable inkjet ink for forming a protective layer during an etching process 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 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.
