Problems solved by technology

[0005] After the present inventor studied the composition of the quick-drying ink composition, it was found that when the red organic pigment was used as the coloring agent in the ink composition, the rheological properties of the ink composition would change greatly during storage, and would become Not suitable for gel pen use, therefore, there are problems in storage stability
[0006] Among the existing quick-drying inks for gel pens, there is no ink for quick-drying gel pens using red organic pigments as colorants

Embodiment

[0074] Hereinafter, the present invention will be described in more detail through specific examples. The following examples are provided to understand the idea of ​​the present invention more easily, and are not intended to limit the specific forms of the present invention.

[0075]

[0076] Prepare red organic pigments, dispersants, defoamers, pH regulators, preservatives and deionized water according to the mixing ratio in Table 1 below, add the prepared components into a container with a stirring device, and stir to obtain After the pigment is fully wetted, use a nano grinder to grind the homogeneous mixture so that the particle size D50 after grinding is less than 250nm, so as to obtain a pigment paste.

Abstract

The present invention provides a gel ink composition. 100 parts by mass of the gel ink composition comprise, by mass, 2-10 parts of a red organic pigment, 5-25 parts of a humectant, 0.1-1.5 parts of apreservative, 0.1-4 parts of a pH adjuster, 1-10 parts of a penetrant, 1-5 parts of a tackifier, 0.5-7 parts of a dispersant, 0.1-0.5 part of an antifoaming agent and 37-90 parts of deionized water,and the penetrant is at least one selected from alkyl sulfosuccinate compounds and oligoethylene glycol alkyl ether compounds.

Description

technical field [0001] The invention relates to the field of neutral ink compositions for gel pens, more specifically to a gel ink composition for gel pens with a quick-drying effect, and a gel pen using the ink composition. Background technique [0002] As a writing tool, the ballpoint pen is widely used in various writing and marking purposes in daily work and life. As consumers' demands for products become more and more diversified, the requirements for various performances of ballpoint pens are also getting higher and higher. [0003] Among them, since ballpoint pens dry slowly when writing, the written handwriting is easily contaminated, so the demand for ballpoint pens with quick-drying effect is increasing. In the past, in order to improve the quick-drying effect, ballpoint pens using dyes as coloring agents have been proposed. However, due to insufficient durability of dyes, the long-term storage requirements cannot be met. On this basis, a ballpoint pen using pigm...
