Abstract
Official abstract text for this publication.
Ink-jet print head for an ink-jet printer including at least a substrate and a photopolymer barrier applied onto the substrate. The photopolymer barrier includes an adhesive first layer and a second layer made of a photopolymerizable material and applied above said first layer. The adhesive first layer is made of a canonically polymerizable material partially polymerized that, when contacted by a water-based ink containing acidic species, is able to further polymerize, thus improving the photopolymer barrier adhesion on the surface of the substrate with time.
First claim
Opening claim text (preview).
What is claimed is: 1. An ink-jet print head for an ink-jet printer comprising: at least a substrate and a photopolymer barrier applied onto said substrate, said photopolymer barrier comprising an adhesive first layer and a second layer made of a photopolymerizable material and applied above said first layer, wherein said photopolymer barrier defines ink passageways and ejection chambers formed on said substrate, and a water-based ink containing acidic species, wherein said…
