PROBLEM TO BE SOLVED: To obtain an ink follower without oil extraction even by preserving at a high temperature when used for a hydrocarbon oily ink containing a solvent made of an aromatic hydrocarbon or the like, by using a polyalkylene glycol derivative, a glycidylether compound or the like for the solvent. SOLUTION: The ink follower is composed of a solvent made of one or more types of a polyalkylene glycol derivative, glycidylether compound and epoxyester, a gelatinizing agent and an additive to be added as needed as indispensable components. Then, the respective compounds of the solvent are each a substance insoluble in or hard soluble in the hydrocarbon solvent made of aromatic hydrocarbon or the like. As the agent, an inorganic compound such as a fine particle silica or the like normally used or a cellulose derivative or the like can be used. Further, various surfactant hard soluble in the solvent of the oily ink can be added as needed. |
