Problems solved by technology

However, this metal powder pigment ink composition for marking pens not only has problems in writing properties such as storage stability and ink flowability, but also has insufficient brilliance of handwriting.
[0004] Therefore, a metal powder pigment ink composition for a marker pen that uses a ketone resin as the resin to achieve improved storage stability and writing properties has also been proposed (see Patent Document 2), but the brightness of the handwriting is still insufficient.

Embodiment 1

[0062] Using the components shown in Table 1 in the amounts shown in Table 1, an aluminum powder pigment ink composition was prepared. The ink composition was coated on the occlusion rate test paper manufactured by Nippon Test Panel Co., Ltd. with a bar coater No. 30 at a speed of 12 cm / sec using a film applicator. After drying, it was manufactured by Horiba Co., Ltd. The manufactured HORIBA hand-held gloss meter Gross Checker IG-310 was used to measure the gloss in the following manner.

[0063] That is, light is irradiated from a light source at an incident angle of 60° to the coating film on the above-mentioned test paper, and the reflected light is received by a receiver at an acceptance angle of 60° to measure its intensity. The board was used as a gloss standard board, and the ratio to the intensity of the reflected light was evaluated as glossiness. When the reflectance of reflected light on a glass surface with a refractive index of 1.567 is 10%, the glossiness is 100...

Embodiment 2~8

[0065] Using the components shown in Table 1 in the amounts shown in Table 1, an aluminum powder pigment ink composition was prepared in the same manner as in Example 1, and the brightness of handwriting was measured in the same manner as in Example 1. The results are shown in Table 1.

Embodiment 9

[0067] Using the components shown in Table 1 in the amounts shown in Table 1, a brass powder pigment ink composition was prepared in the same manner as in Example 1, and the brightness of handwriting was measured in the same manner as in Example 1. The results are shown in Table 1.

Abstract

(Problem) To provide a metal powder pigment ink composition for an oil-based marker pen that gives handwriting with improved gloss. (Solution) The metal powder pigment ink composition for oily markers according to the present invention is a metal powder pigment ink composition for oily markers comprising an organic solvent, a metal powder pigment, and a resin, wherein the resin is selected from ketone resins, A combination of at least one first resin selected from hydrogenated rosin resins and ultra-light rosin resins, and at least one second resin selected from acrylic resins, styrene-acrylic resins, and styrene-maleic resins.

Description

technical field [0001] The present invention relates to a metal powder pigment ink composition for oil-based markers, and more specifically, to a metal powder pigment ink composition for oil-based markers that gives marks (ie, handwriting) with improved gloss. Background technique [0002] Conventionally, various metal powder pigment ink compositions for marking pens using metal powder pigments such as aluminum powder and brass powder as pigments are known. When writing on a writing surface using such an ink composition, the metal powder pigment is fixed to the writing surface by the resin, giving shiny handwriting. [0003] As an example of such a metallic powder pigment ink composition for a marking pen, it is known to use propylene glycol monomethyl ether as an organic solvent and phenolic resin as a resin together with an aluminum powder pigment surface-treated with a fatty acid (salt). resin obtained (refer to Patent Document 1). However, this metal powder pigment ink...
