Abstract
The present invention provides an inkjet ink and a hiding layer coating agent that contain radical polymerizable components including a polyfunctional monomer that includes a high Tg polyfunctional monomer with a glass transition temperature Tg of not less than 40° C. at a ratio of not less than 30 mass % and a monofunctional monomer, a volatile solvent, and a photo-radical polymerization initiator, with a ratio of the monofunctional monomer being 5 to 70 mass % in the radical polymerizable components and a ratio of the volatile solvent being 50 to 400 mass % with respect to the radical polymerizable components and are excellent in dispersion stability due to not containing (excluding) a white pigment such as titanium oxide, etc., and enable printing of a white or colored character having a high hiding property equivalent to that in a case where the white pigment is contained.
