(Field of Industrial Application) The present invention relates to a water-based pigment ink for writing instruments, and more particularly to a water-based pigment ink for writing instruments that has excellent lubricity and dispersibility and prevents handwriting from blurring as much as possible. (Prior Art) Water-based pigment inks for writing instruments have traditionally been used in place of water-based dye inks because they have superior water resistance and light resistance compared to water-based dye inks. However, it is necessary and sufficient for the aqueous pigment ink for writing instruments to have a pigment as a coloring agent dispersed in the form of fine particles, and that the dispersion be stable over time. Furthermore, when a water-based pigment ink for writing instruments is used in a ballpoint pen, the pigment wears down the ball seat of the tip that comes into contact with the ball, so it is necessary to reduce this wear as much as possible. To disperse pigments in water-based pigment inks for writing instruments, water-soluble or dispersible acrylic resins, maleic acid resins, and various activators are used, and although this objective has been achieved to some extent, it reduces the abrasion resistance. That is difficult. As a solution to this problem, attempts have been made to add lubricants to water-based dye inks, but these have the following problems. (Problems to be Solved by the Invention) The addition of ethylene oxide-added acetylene alcohols described in JP-A-56-16775 and JP-A-57-18772 increases the viscosity of water-based pigment inks for writing instruments. Makes the discharge worse. Furthermore, the anticorrosion effect of the triple bond of acetylene alcohol is also reduced. The phosphoric acid esters described in JP-A-56-99269 and JP-A-57-5773 have a lubricating effect when added, but because they have the properties of activators, the surface tension of the resulting water-based pigment ink for writing instruments is The handwriting on the paper smudges. The fatty acid esters of polyhydric alcohols described in JP-A-57-92067, JP-A-59-115369, JP-A-60-4574, and JP-A-60-49074 are sparingly soluble or insoluble in aqueous ink solvents, In water-based pigment inks, it gradually hydrolyzes, resulting in an imbalance in the pigment dispersion system and agglomeration of the pigment. It had the following problems. (Means for Solving the Problems) The present inventors have improved the lubricity of water-based pigment inks for writing instruments, and have improved the lubricity of water-based pigment inks by reducing agglomeration of pigment particles due to decreased dispersion stability of the pigment and decreasing surface tension. As a result of intensive research to obtain a lubricant that can prevent handwriting from smearing as much as possible, the present invention was completed by discovering that an organic phosphoric acid ester represented by the following general formula () is effective. That is, the present invention provides an aqueous pigment ink containing at least a pigment, a dispersant, a water-soluble solvent, and water,
The gist of the present invention is a water-based pigment ink for writing instruments characterized by containing an organic phosphoric acid ester represented by the following general formula (). <General formula> (In the formula, R is a chain saturated hydrocarbon group or a chain unsaturated hydrocarbon group having 4 or more carbon atoms, and n is 1 or 2
, M represents an alkali metal, ammonium or alkanolamine salt. ) (Function) Unlike phosphate ester surfactants, the organic phosphate ester used in the present invention has 1 to 2 chain saturated hydrocarbon groups or chain unsaturated hydrocarbon groups having 4 or more carbon atoms in the ester moiety. However, since the remaining phosphoric acid groups are soluble in water-based pigment inks for writing instruments, it is important that they become alkali metal, ammonium salts, or alkanolamine salts, which are effective not only as lubricants but also as extreme pressure additives. It also exhibits the effect of a rust preventive agent. Therefore, the aqueous pigment ink for writing instruments of the present invention to which the organic phosphate ester of the present invention is added,
Because the ink has sufficient dispersion stability both on its own and in writing utensils, settling and agglomeration of pigment particles are prevented as much as possible.Furthermore, the wear of the tip by the ball is small, so it can be used to write long-lasting handwriting with little smearing. Obtainable. (Structure of the Invention) Next, each component of the present invention will be explained. As the pigment used in the present invention, conventionally known inorganic pigments and organic pigments can be used, and their forms such as powder and aqueous paste can be used without problems. The amount of these pigments used is preferably 3 to 20% by weight based on the total amount of the ink. Dispersants used in the present invention include dispersible or water-soluble acrylic resins, polyvinyl alcohol, silicone resins, and various surfactants such as anionic surfactants, nonionic surfactants, cationic surfactants, etc., either singly or in combination. A combination of the above is effective, and the amount used is preferably 0.5 to 20% by weight based on the total amount of ink. Next, regarding the organic phosphoric acid ester which is the gist of the present invention, any organic phosphoric acid ester represented by the above general formula () can be effective. That is, the ester part of the phosphoric acid ester (R in the general formula ()) is a chain saturated hydrocarbon group or a chain unsaturated hydrocarbon group having 4 or more carbon atoms, and specifically, butyl, amyl, hexyl, heptyl, Chain saturated hydrocarbon groups such as octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl, and chain unsaturated hydrocarbon groups such as butenyl, hexenyl, oleyl, etc. monoester, where the number of ester groups (n in general formula ()) is 1 or 2;
It is a diester, and the salt (M in the general formula ()) is an alkali metal, ammonium or alkanolamine salt, specifically an alkali metal such as lithium, sodium, potassium, ammonia,
Water-soluble ammonium salts such as methylamine and ethylamine, monoethanolamine, diethanolamine, triethanolamine, N,N-dimethylethanolamine, N,N-diethylethanolamine, propanolamine, butanolamine and its ethylene oxide, butylene oxide It is an alkanolamine salt such as an adduct. The organic phosphoric acid esters represented by the above general formula () can be used alone or in combination, and the amount used is preferably 0.1 to 10% by weight based on the total amount of the ink.
More preferably, it is 0.5 to 8% by weight. The same effect can be observed whether the organic phosphoric acid ester is added before or after the preparation of the aqueous pigment ink for writing instruments. As the water-soluble solvent used in the present invention, non-volatile water-soluble solvents such as ethylene glycol, diethylene glycol, propylene glycol, and glycerin can be used, and the amount used is 5% based on the total amount of ink.
~30% by weight is desirable. Water is used as the main solvent, and the amount used is 40 to 80% by weight based on the total amount of ink. In addition to the above-mentioned components, hygroscopic substances such as urea and urea derivatives, rust preventive agents, anti-mold agents, etc. can also be used as necessary. The water-based pigment ink for writing instruments of the present invention consists of the above-mentioned components, and can be easily produced by mixing and grinding using a known method such as a ball mill, homomixer, sand grinder, speed mill, roll mill, etc. It will be done. (Example) Next, the present invention will be explained in more detail with reference to Examples, in which "parts" indicate "parts by weight". Example 1 Carbon black 10 parts Monoethanolamine salt of styrene-methacrylic acid copolymer (weight ratio 50:50) 10 parts Dioctyl phosphate monoethanolamine salt 1 part Ethylene glycol 20 parts Benzotriazole 0.5 parts Water 58.5 parts The above ingredients In addition to the ball mill, it is dispersed for 100 hours,
