  • High elongation thermoforming ink-jet ink
    Patent number: 9458333
    Abstract: An energy-curable ink or coating composition comprising: a monofunctional urethane monomer, such as a monofunctional urethane acrylate monomer; a monofunctional monomer; and, optionally, a colorant, photoinitiator, stabilizer, surfactant and/or a vinyl resin, for use as a thermoforming ink or coating that, when printed onto a substrate (1), elongates on thermoformation of the substrate (3) to adopt the shape of a mold (2), a method of printing on a thermoforming substrate using such an ink or coating and a printed thermoformed article (4).
    Type: Grant
