To provide an ink composition for forming a fine pattern, which is capable of accurately forming an optimum (fine) image for various electronic components by a relief reversal printing method.
The ink composition for forming the fine pattern is used in the relief reversal printing method comprising the steps of: forming an image on a blanket surface by pressing an ink coating film uniformly formed on the blanket surface onto a relief printing plate so that a pressed part is transferred to the relief printing plate and removed; and transferring the same to a printing substrate. The ink composition comprises a granular component, a pigment dispersant, a curable resin, an organic solvent and a surface energy regulator, provided that the pigment dispersant contains an acrylic block copolymer.
