Abstract:
1. An active energy ray-curable ink comprising: polymerizable compounds, wherein the polymerizable compounds contain a monofunctional polymerizable monomer, a homopolymer of which has glass transition temperature of 90° C. or higher, and wherein a cured product obtained by forming a coating film having an average thickness of 10 μm on a polycarbonate substrate using the active energy ray-curable ink, and 15 seconds later, and applying active energy rays having a light quantity of 1,500 mJ/cm (1) a stretchability of the cured product, which is represented by the following equation, is 2 or greater, when the cured product is stretched by means of a tensile tester at a tensile speed of 20 mm/min, and temperature of 180° C., and (2) adhesion between the polycarbonate substrate and the cured product as measured by a cross-cut test in accordance with JIS K5400 is 70 or greater.
