Embodiment 1

[0113] Next, the present invention will be specifically described by way of examples and comparative examples, but the present invention is not limited thereto.

Embodiment 1～6 and comparative example 1～5

[0115] Each oil-based ink composition for writing instruments was prepared by the following method.

[0116] "Preparation of Oily Ink Composition for Writing Instruments"

[0117]

[0118] Aluminum pigment (13G: floating type, manufactured by Asahi Kasei Corporation, 6 parts by mass), dye (Spilon Red C-GH, manufactured by Hodagaya Chemical Co., Ltd., 3 parts by mass), and nitrocellulose as resin were mixed by stirring. (DHX5-10, manufactured by NOBEL Corporation, 5 parts by mass), hydroxyl-containing polyether-modified polydimethylsiloxane [BYK-SILCLEAN3720, manufactured by BYK Corporation, active ingredient 25%, solvent propylene glycol monomethyl ether (PGM), 4 parts by mass (1 part by mass of active ingredient, 3 parts by mass of propylene glycol monomethyl ether)], and propylene glycol monomethyl ether (57 parts by mass) as solvent, ethanol (20 parts by mass), and benzyl alcohol (5 parts by mass) are mixed , Prepared 100 parts by mass of the oil-based ink composition fo...

Embodiment 2

[0120] The mass parts of hydroxyl-containing polyether-modified polydimethylsiloxane (BYK-SILCLEAN3720, manufactured by BYK Company) was changed to 12 mass parts (3 mass parts of active ingredients, 9 mass parts of propylene glycol monomethyl ether), and the propylene glycol monomethyl ether Except having changed the mass parts of methyl ether into 49 mass parts, it carried out similarly to Example 1, and prepared 100 mass parts of the oil-based ink composition for writing instruments of Example 2.

Abstract

An oil-based ink composition for writing utensils, which exhibits good writing performance with respect to wiring surfaces formed of various materials, while having improved friction resistance, namely good resistance of handwriting written therewith to repeated rubbing or to rubbing with stronger forces; a writing utensil which uses this oil-based ink composition for writing utensils; and an air brush unit which uses this oil-based ink composition for writing utensils. An oil-based ink composition for writing utensils according to the present invention is characterized by containing at least an aluminum pigment, a coloring agent, a resin, an organic solvent and a polydimethyl siloxane, and is also characterized in that: the polydimethyl siloxane has a polyether-modified group at both ends; and the sum of hydroxyl groups of the polyether-modified groups is 3 or more.

Description

technical field [0001] The present invention relates to an oil-based ink composition for writing instruments, a writing instrument using the same, and a spray gun unit using the same. Background technique [0002] Oil-based inks currently used in marker pens use various colorants. As one of them, by using metal powder represented by aluminum pigment, a metallic luster is given to the drawn line. Since the aluminum pigment has a total length of several μm, it has a property that it is easily peeled off by wiping with fingers or the like unless sufficient fixability is imparted to the writing surface. [0003] In addition, writing objects based on writing instruments using oil-based ink compositions are not limited to ordinary liquid-permeable paper, and include paper, plastic, glass, metal, etc. coated with a resin on the surface. For such various objects, oil-based inks are also required to have sufficient fixability and provide handwriting that can withstand wiping. [0...
