<p>PURPOSE:To obtain a printing ink composition for offset rotary press, containing a specific amount of a high-molecular weight organopolysiloxane which is liquid at normal temperature, effective in preventing the adhesion of ink to a non- image area composed of non-sticking layer and having excellent printability and printing effect. CONSTITUTION:The objective ink composition contains 0.1-10wt.% of an organopolysiloxane having a molecular weight of 1,000-100,000 and exhibiting liquid state at normal temperature.</p> |
