<p>PURPOSE: To obtain a stamp ink which is persistently stable at a viscosity suitable for stamping and increased in the speed of infiltration into paper by bringing it closer to a Newtonian fluid and which, as the result, has good fixability and sets quickly. CONSTITUTION: This ink consists of, based on the total ink composition, 30-97wt.% oil-modified alkyd resin component obtained by the condensation of terephthalic acid, a polyhydric alcohol and an oil or fat and having an oil length of 60 to 90, 0-50wt.% solvent, and 1-30wt.% coloring agent.</p> |
