Abstract:
The present invention relates to 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, characterized in that said adhesive first layer is made of a cationically polymerizable material partially polymerized that, when contacted ny a water-based ink containing acidic species, is able to further polymerize, thus improving the photopolymer barrier adhesion on said surface of said substrate with time, the present invention also relates to a process of manufacturing said ink-jet print head and to its use in combination with a water-based ink containing acidic species.
