Using InkRes® 33 a partial replacement of the self crosslinking acrylic was achieved with no effect on adhesion to film substrate. Adhesion was tested via ASTM test F2252. Higher loading was not possible due to viscosity increase.
Re-wettability: Benchmark formula dried-in faster producing an inferior print quality versus the InkRes® 33 modified formula.
Colour strength was improved with the InkRes 33 modified formula versus the benchmark.
