Abstract
An ink follower composition to be provided at the rear end of an ink held directly in an ink container of a writing instrument and capable of going forward with consumption of the ink. The composition comprises at least one selected from an ethylene-α-olefin co-oligomer, an α-olefin oil, a purified mineral oil and a polybutene, and added thereto a specific fatty acid amide. This composition can simultaneously satisfy the two important performances conflicting with each other, the ink flow-back preventive performance and the ink follow-up performance.
