<p>A printing ink composition that not only exerts an excellent anti-blocking effect but also is free from any hickey phenomenon, resolving the problems of plate stain, blanket stain, etc. There is provided a printing ink composition wherein there are dispersed composite particles of 2 to 8 µm volume-average particle diameter in which the volume content of solid polymer particles of > 10 µm particle diameter is = 5 vol.%. The composite particles (A) each comprise solid polymer particle (B), such as wax, insoluble in the printing ink and, mainly adhering to the periphery thereof, inorganic microparticles (C) of 5 to 1000 nm average particle diameter.</p> |
