<p>PROBLEM TO BE SOLVED: To obtain a printing ink composition capable of suppressing slipping of printed papers and preventing accidents such as load falling, slip down, etc., in piling printed papers, post processing of bookbinding, etc., and improving the productivity by blending an offset printing ink with a friction resistance agent and a slip resistance agent. SOLUTION: This composition is obtained by blending an offset printing ink composition with (A) 0.1-10 wt.% of a friction resistance agent and (B) 0.1-10 wt.% of a slip resistance agent. Fine particles of a rigid resin such as polyethylene or wax particles are preferable as the component A. Elastic organic particles such as a polypropylene rubber or inorganic fine particles such as talc are preferable as the component B. The component A and the component B have preferable 1-10μm average particle diameter. The objective resin preferably comprises 20-50 wt.% of a solid resin such as rosin-modified phenol resin, 0-30 wt.% of drying oil such as linseed oil and 10-60 wt.% of a solvent such as normal paraffin besides the component A and the component B.</p> |
