Abstract
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.
