Abstract
A dry planographic printing ink composition which comprises a vehicle for an ink, a pigment and a solvent, characterized by using as a portion of the vehicle 1 to 40% by weight of silicone modified alkyd resin containing 5 to 50% by weight of organopolysiloxanes represented by the average composition formula: ##EQU1## WHEREIN R.sup.1 stands for a mono-valent unsubstituted hydrocarbon group containing 1 to 4 carbon atoms, R.sup.2 stands for a hydrogen atom or mono-valent hydrocarbon group containing 1 to 4 carbon atoms, n is an integer of 1.0 to 2.0, m is an integer of 0.1 to 2.5, but n + m is less than 4. The ink composition is a very favorable dry planographic printing ink composition having a practicable printing adaptability.
