PURPOSE: An ink capable of printing a micropattern, a printed product using the ink and its preparation method are provided, to obtain a printed product containing a cured coating film having a micropattern on a substrate without employing very expensive process such as a process required in case of using an ink containing a photosensitive resin and without generating a large amount of waste liquid. CONSTITUTION: The ink capable of printing a micropattern comprises 100 parts by weight of a resin component and 30-300 parts by weight of a filler, wherein a cured coating film obtained by screen printing the ink and heating the printed one has a slope angle of 15 degree or more to the printing surface. Preferably the ink has a complex viscosity (η*) of 10,000-300,000 poise at a frequency of 1 rad/sec and a complex viscosity (η*) of 1,000-30,000 poise at a frequency of 10 rad/sec at a printing temperature. Preferably the resin component shows a thermosetting reaction at a temperature range of 100-210 deg.C, and the heating is carried out at a temperature of 60-210 deg.C.
