INK FOR PRINTING, PRINTED MATTER, PRINTING METHOD, AND PRINTER

摘要

An ink for printing, characterized by comprising a photo-curing high polymer precursor, a photopolymerization initiator, and inorganic particulates of 0.1 mu m or less in average grain size of 3 to 8 parts by mass per a high polymer precursor of 100 parts by mass, characterized in that a viscosity at a shear rate of 5 (1/s) is 8 to 75 (Pa.s) and a viscosity at a shear rate of 20 (l/s) is 3 to 25 (Pa.s) at 25 DEG C, and a thixotropic index value is 1.5 to 3.5, whereby, by using the ink for printing, the letters, figures, symbols, and graphics of 0.2 mm or more in thickness can be printed at high speeds without affecting a printed base material, a printed matter characterized in that the ink for printing is printed on the surface of the printed base material and cured can be provided and, since the ink for printing is suitable for providing a braille printed matter, the braille printed matter having braille printed on the surface thereof can be provided by printing the ink for printing in dot shape on the surface of the printed base material and curing the ink.
