Abstract
Ink deposited on a substrate by an ink-jet arrangement to form a protective layer includes hardenable oligomer, hardenable monomer selected from a group including alkoxylated and/or poly-alkoxylated acrylic monomers comprising one or more di- or tri-acrylates, and a photoinitiator. The oligomer has a room temperature viscosity greater than 1 Pa·s. The oligomer to monomer weight ratio is between 1/6 and 1/25. The ink has a room temperature viscosity between 15 and 22 mPa·s and between 5 and 2 mPa·s at 60° C., and a room temperature surface tension between 15 and 28 mN/m. The photoinitiator is activated by a UV source having an appropriate wavelength and intensity.
