Embedded image The fluorescent material represented by the formula (1) emits red light of 600 to 650 nm when irradiated with ultraviolet light of 254 to 390 nm, but does not emit light when not irradiated with ultraviolet light, so that it is not easy to visually discriminate and is useful as a material of so-called blinding ink. . The fluorescent material is 4,4,4-trifluoro-1-
(2-thienyl) -1,3-butanedionate europium chelate compound, which does not emit light under visible light but emits red light under ultraviolet light,
The emission intensity is high and the light resistance is excellent. The fluorescent material has almost no solubility in water, is difficult to form an ink, and is soluble in a volatile ketone-based solvent other than the alcohol-based solvent, and penetrates into the printed material to penetrate the printed surface. Fluorescent material does not easily adhere, but is extremely finely dispersed in alcoholic solvents (particle size of 1 to 100 nm)
Therefore, the printed ink hardly penetrates into the printed matter, the fluorescent material adheres to the printed matter surface, and the emission intensity on the printed matter surface, especially on the black surface, is large.
