Description

technical field [0001] The invention relates to the technical field of ink, in particular to an ink for a gel pen. Background technique [0002] The gel pen is a commonly used writing tool. At present, most of the commercially available gel pens use imported gel ink that can prevent freezing, and some gel pens that use domestic gel ink that can prevent freezing are used during use. On the other hand, there will often be problems such as clogging of the pen head and poor writing, and even the situation that the pen core cannot be continued to write when less than one-fifth of the pen core is used up. An important reason for the above phenomenon is that the domestic antifreeze The ink used for gel pens has poor freeze-resistant storage stability and is prone to sedimentation, causing clogging of the pen head and ultimately making it impossible to write smoothly. Contents of the invention [0003] In order to solve the above technical problems, a technical solution adopted b...
