PURPOSE:To the titled composition effecting prevention of adherence of the same on the inner surface of the ink cartridge as much as possible, by incorporating hard-volatile organic liquid as ester. CONSTITUTION:The objective composition as an aqueous ink with a viscosity 50-200CPS at 25 deg.C in cartridge, can be obtained by incorporating (A) as base agent, a hard-volatile or non-volatile organic liquid selected from hydrocarbons (e.g., liquid paraffin) with (B) a gelling agent (e.g., particulate silica) and (C) a pentaerythritol fatty acid ester (e.g., pentaerythritol laurate). |
