[0052] Water-soluble resin (trade name: HPD-96)
[0053] Acrylic resin 4.0% by weight
[0054] Isopropanol (4.3kPa / 20°C) 5.0% by weight
[0055] Water 86.0% by weight
[0056] Anti-rust lubricant (trade name: A-215C) 0.5% by weight
[0057] Triethanolamine 1.0% by weight
[0058] Oil-in-water resin emulsion (trade name: Jion Clear 7001)
[0059] Acrylic emulsion 1.5% by weight
[0060] Wettability improver (trade name: Dynoll 604) 0.8% by weight
[0061] 1,2-Benzisothiazolin-3-one 0.2% by weight
[0062] Pigment Pigment Black 7 as a colorant, water as a solvent, and acrylic resin with a molecular weight of 16,500, a glass transition point of 102°C, and an acid value of 240 as a water-soluble resin that has both pigment dispersing function and handwriting fixing performance. Trade name In HPD-96 (manufactured by Johnspon Polymer Co., Ltd.), predetermined amounts of each component were accurately weighed, and the pigment was unifor...
Embodiment 2
[0064] The green pigment Pigment Green 7 used as a colorant, the styrene acrylic emulsion with a minimum film forming temperature of 15°C as a handwriting fixation and water resistance improver, trade name Jionclell 775 (manufactured by JionSompolima Co., Ltd.), except Except as shown in Table 1, operate in the same manner as in Example 1 to obtain inks for water-based ballpoint pens with green handwriting and appearance. In addition, for the product names HPD-96 and Jion Clear 775, consider the amount of effective solid content. design. In addition, the viscosity of the ink at 20° C. was 10.0 mPa·s.
Embodiment 3
[0066] As a handwriting fixation and water resistance improver, a vinyl acetate-based emulsion with a minimum film-forming temperature of 16°C or below, trade name Boncoat 2610 (manufactured by Dainippon Inki Chemical Industry Co., Ltd.), was used as a solvent at a vapor pressure of 20°C. Be the ethanol of 5.9kPa as alcoholic solvent, except as shown in table 1, operate similarly with embodiment 1, obtain handwriting, outward appearance all be the ink for water-based ball-point pen of green, in addition, for trade name HPD-96, ボンコ one ト2610, consider the amount of effective solids to design the ink. In addition, the viscosity of the ink at 20° C. was set to 15.0 mPa·s.
