発明の名称 (英語) INK SET, PRINTED MATTER AND PRINT METHOD
発明の概要(英語) This ink set comprises a first ink composition which includes a fluorescent rare earth metal complex that has an m-dentate ligand and that is not chiral and a second ink composition which includes an n-dentate chiral ligand that displaces the m-dentate ligand when coming into contact with the first ink composition and generates a rare earth metal complex with circularly-polarized luminescence properties that is different from the fluorescent rare earth metal complex, wherein m is an integer of 1-3 and n is an integer of 2-4 and greater than m. By using the above ink set, a region having circularly-polarized luminescence properties can be formed on only a portion of a fluorescent printed matter. Thus, the presence of the region with circularly-polarized luminescence properties is not easily revealed and an identification mark that is not susceptible to forgery or alteration can be provided.
