<p>PURPOSE:To provide the oily marking pen ink composition containing a coloring agent, an organic solvent, a resin, and a polyether-modified silicone oil. little in thre bleeding of pen marks and not generating the scratching of pen marks when used on the non-absorbing surface of article including glass and coated paper. CONSTITUTION:0.5-25.0wt.% of a coloring agent (e.g. rhodamine), 50.0-95.0wt.% of an organic solvent (e.g. n-propyl alcohol), 1.0-15.0wt.% of a resin, and 0.01-8.0wt.% of a polyether-modified silicone oil exemplified by the reaction product produced by subjecting a dimethylpolysiloxane having Si-H groupd and a polyether having carbon-carbon double bonds at the molecular ends to an addition reaction in the presence of a platinum catalyst to provide the objective oily marking pen ink composition not generating the bleeding and scratching of pen marks when used on the surface of a non-absorbing article such as glass and further on the surface of coated paper relatively near to the non- absorbing article.</p> |
