  • Patent number: 7189766
    Abstract: The printing ink of the present invention is characterized by containing a photo-curable high polymer precursor, and a photopolymerization initiator, and containing 3 to 8 parts by weight of inorganic fine particles having a mean particle size of 0.1 ?m or less to 100 parts by weight of the high polymer precursor. Moreover, the printing ink of the present invention is characterized by having a viscosity at a shear rate of 5 (l/s) of 8 to 75 (Pa·s), a viscosity at a shear rate of 20 (l/s) of 3 to 25 (Pa·s), and a thixotropic index value of 1.5 to 3.5. As a result of using this printing ink, letters, figures, symbols, graphics, etc., having a thickness of 0.2 mm or more can be printed rapidly without affecting the printed base material.
